Currently in South America and planning my move back to the US once a role is secured (whether in San Francisco or another city) to avoid relocating twice.
Due to high interest in my work with recursive self-improving agents, I've shared an example repo at https://github.com/adam-s/agent-tuning. I'm always open to discussing how I optimize agents for complex, repetitive workflows.
I bring 13 years of full-stack UI development experience alongside deep expertise in browser automation and agents, which I've been engineering since 2018. This blend makes me particularly strong in QA automation engineering and complex frontend architecture.
Notable projects include custom legal document management dashboards and a drag-and-drop CRM email builder for social marketing campaigns. As a consultant and full-time engineer, I’ve led 0-to-1 product development across fintech, streaming, real estate, edtech, marketing, and media. Having worked at companies ranging from a 130-person AI organization to a scrappy 7-person team, I thrive most in fast-paced, high-ownership environments.
Engineer and founder, 18+ years. Most recently built Screenshot to Code (open source, 73K+ GitHub stars) and Pico, scaled solo to $200K ARR and 330K users. Before that: one of 5 people at early Notion, founder of PeerCDN (acquired by Yahoo), Yahoo video, Palantir (intern work Palantir patented). Stanford CS.
Looking for a senior IC role on a strong engineering team in the AI / AI-coding / robotics space — ideally a company that genuinely embraces AI-assisted development.
Software Engineer and recent Computer Science graduate (Math minor) with hands-on experience co-founding initiatives and shipping full-stack applications. Tech stack includes FastAPI, React, TypeScript, PostgreSQL, and familiarity using Linux environments.
Interested in full-stack, backend, or systems-focused software engineering roles where the focus is building functional, reliable products and APIs. Open to full-time remote or onsite opportunities.
Location: Greater New York (US Citizen)
Remote: Yes
Willing to relocate: No
About: I am a Generative AI Engineer who also happens to be pretty hands-on across the full stack development. Most of my recent work has been building RAG pipelines, AI agents, and natural language search — using LangChain, LangGraph, and vector databases like Pinecone and ChromaDB — with OpenAI, Anthropic, and Gemini APIs under the hood. I care deeply about shipping GenAI features that hold up beyond the demo stage.
Beyond GenAI, I am working on the full stack — React/TypeScript on the frontend, Node.js or ASP.NET Core APIs on the backend, and AWS/Azure for infra. I like owning things end-to-end and building software that's simple and reliable.
Senior software engineer with nearly a decade of experience, previously at Automattic on the WooCommerce Core team. I worked on Cart and Checkout Blocks, payment-state architecture, payment-gateway compatibility, and the migration of the E2E suite from Puppeteer to Playwright.
I am strongest in mature or inherited products where a wrong change can break checkout, third-party integrations, application state, or release confidence. My recent independent work includes WordPress/React plugins and hardening sandbox and proxy behavior for an AI app builder.
Open to full-time, contract, part-time, or short paid stabilization work. Available immediately.

Applied physicist and engineer, 15+ years. Put me on a messy, physical,
high-consequence problem that crosses disciplines and has to ship — not demo.
Recent: 6 years at Agilent building production ML over instrument telemetry —
fleet-wide failure prediction, and a RAG/LLM system for 300+ field engineers taken
from prototype to production (including the confidence logic for when it answers vs.
hands off to a human). Cut data-prep time 8x.
Before that I built scientific instruments from scratch — a fiber-based STED
nanoscope and an OCT microscope — so I know data from the sensor up, not just after
it lands in a warehouse. Earlier: DoD hardware reliability (former TS/SCI), precision
timing, published detector-physics work.
Strongest where software meets the physical world: instrumentation, sensor data, ML
that has to be right because being wrong has consequences. I own problems end to end,
and I'll tell you when the result isn't trustworthy yet.
Open to full-time or contract. Health/medical-device mission a strong plus.
Data scientist with 4+ years of experience delivering production machine learning solutions to top pharmaceutical laboratories. I am able to use LLMs intelligently to create novel models with qualitative accuracy, where LLMs alone would make something that is accidentally correct at best. I have the aptitude for iterating fast in a startup environment, I was able to deliver a working product years before our closest competitor and those models have prevented millions of dollars in losses in the past 3 years with more to come.

Résumé/CV: https://personachat.chat (live product; PDF CV on request)
Email: info@personachat.io
I build and run PersonaChat (personachat.chat), an AI character chat platform on Next.js and Supabase — live since 2025, built and operated solo.
Production LLM work rather than demos: streaming chat over the Vercel AI SDK; a long-term memory layer with append-only writes and invalidate/supersede semantics, idempotency keyed on source turn ID so a dropped stream never duplicates a turn; a relationship engine holding state across sessions that feeds back into generation; and the same character system running through a Discord surface, which forced the state logic out of the components into a shared layer.
I also instrument and read my own funnel in Postgres rather than guessing, and I run Claude Code daily against structured specifications rather than prompts — agents write most of the code, the spec and the review are the job.
Open to full-time or contract. Full overlap with European hours, mornings with US Eastern.

AI-assisted Full-Stack TypeScript developer looking for a remote frontend/full-stack/implementation role.
I’m strongest at taking a loosely defined product task and pushing it all the way to a working result: codebase research, implementation, debugging, testing, deployment, and post-deploy fixes.
My main project is a production CRM built with Next.js/TypeScript/Node: authentication, per-user data isolation, projects and financial tracking, analytics, multi-currency support, an LLM assistant with persistent conversations, CI, automated tests, backups, and deployment on a Linux VPS.
I’ve also built automation/data-processing tooling for 20k+ structured records, worked with REST integrations and Bitrix24 data, and debugged real deployment issues across APIs, SMTP, builds, environment configuration, Nginx and PM2.
I use coding agents heavily, but not as a black box: I inspect the existing codebase, define the scope, review diffs, run type checks/tests/builds, reproduce bugs and verify the result manually before calling a task done.
I’m not looking for a role where “junior” means only converting Figma into components. I’d like to work close to the product and own real problems across frontend, backend, integrations, automation and internal tooling.
Open to full-time work and serious contract opportunities.
SEEKING WORK | California, USA | Remote | Contract / Fractional

22, self-taught. Won a $100K Meta Llama Impact Grant for Bluai and
presented it at LlamaCon on 2025
Bluai (https://play.google.com/store/apps/details?id=com.bluai.app&...) is a hurricane early-warning app live on Google Play in Mexico,
built offline-first because during a hurricane the network is the first
thing to go. An online RAG pipeline and an on-device Llama 3.2
(ExecuTorch, NPU-accelerated) sit behind one interface, picking 1B or 3B
based on device RAM, so the UI never knows which brain answered. When
everything is down it falls back to Bluetooth/Wi-Fi mesh chat over a
multi-hop wire protocol.
Email me one paragraph about something broken or missing in
your product. I'll build a working prototype and send you the repo plus a
short video of it running, within 48 hours. Free. No call, no interview,
no invoice. If you like it, we talk. If not, you keep the code.
Flexible on compensation for the right team. I'm optimizing for who I'd
be learning from, more than thinking in numbers.
I build LLM systems that run in production. The clearest example is live: pick a sector at https://demo.consentleads.uk and message it the way a customer would. Nothing is scripted. It runs on a free-tier ARM box behind a Cloudflare tunnel, is multi-tenant and has users, and nine scheduled jobs keep it going unattended.
If opt-out detection misses a phrase, the system keeps emailing someone who asked it to stop, and nothing crashes or alerts. So the suppression gate fails closed, and the eval fixtures cover that path and reply triage.
I also wrote claimcheck (MIT, https://github.com/visione4906/ctaio-claimcheck): give it a document and a codebase and a second agent has to prove every claim against the source with file and line citations, or the build fails. I built it after an outside review of my own writing turned up claims the code did not support.

I turn unclear product problems into useful, well-designed software. I talk to customers, turn what I learn into product and technical specs, design the workflows and interface, build the system, then help launch, market, and support it. That breadth is my strongest skill: it keeps the customer problem in view throughout.
At Flowstate, I took a workforce-planning SaaS from blank repo to paid pilot in 10 weeks as sole engineer-designer. I currently own product design, backend, mobile apps, Stripe Connect payments, AI-assisted listing tools, and infrastructure for a US trading-card marketplace.

SEEKING CONTRACT WORK - Forward deployed engineer, remote, email in profile. Location: West Coast, remote only.
I'm a forward-deployed engineer. My background is 15+ years of data science, but I focus on solving problems. I work in messy, ambiguous, regulated environments. Often at a client's site, inside their systems and their data. I excavate unmapped data, learn how the team works, and ship tools that stay in production.
Deployed and still running today: Legal clause extraction and validation; site corrosion detection and management; routing and predictive-maintenance systems that stayed in service.
I compress engineering, data, and modeling into one function, owned end to end. I show up, figure out what needs to be built, and make it work.
Tooling: ML/AI, LLMs, and the engineering around them: evals, determinism, observability, guardrails. The tech is just a tool, The hard part is knowing what to build.
If you have a messy, ambiguous problem that needs someone who can embed and ship, my email is in my profile.
EDIT: Corrosion detection so people don't think I detect rust code. (Nothing wrong with that though)
Trustworthy output from untrustworthy data. I build systems that catch what's silently wrong — a dead sensor nobody noticed, contradictory records, a garbled scan, a confidently-wrong model — so it surfaces as a flag today, not a six-month catastrophe.
I use LLMs where they earn their place (development, meaning, embeddings, plain-language access to jargon-locked data) and keep them out of decisions and the data flow, which stay deterministic and verifiable. An LLM can help you find the answer; it can't be the answer.
Senior systems engineer, multiple AI cycles of judgment on what survives the hype and where it breaks. Currently turning messy Polish legal PDFs into a correctness-checked graph — the hard part is the verification, not the AI. Previously I built a legislative-notification service that ran autonomously in production for over three years before I retired it. I've written about where AI coding agents actually fail and why verification is the real work: https://walat.eu
Best fit when: correctness matters, the data is real-world-messy, and you want someone who names what doesn't work and why.
Hi, I'm Jonathan, a PhD physicist who moved into infrastructure.

Most of what I've built recently is open source. The one with real users is decypharr, a media gateway that streams files over a FUSE layer, where I've done deep work on goroutine leaks, lock contention, and caching. I also build a handful of smaller Go tools, from a multi-protocol file server to a protobuf schema registry, all on my GitHub.
Full stack engineer, 2+ years, currently lead developer on a real-time broker app.
Highlights:
- Shipped Floret Analysis end to end — a React Native trading app live on both the App Store and Play Store. Live WebSocket market data, dynamic charting, biometric auth, push notifications, native module bridging: https://apps.apple.com/pk/app/floret-analysis-for-pmex/id674...
- Scaled Anewswire, a Django/Next.js press platform, past 20,000 active users with RSS pipelines and a custom CMS.
- Architected Contfly, a Nest.js microservice platform integrating 6+ social APIs behind a gateway.
- LLM tooling in production, not just in the editor: Claude Code as my primary driver, bulk generation on the Anthropic Batches API, and a deterministic metadata layer over ~700 generated pages — built specifically to bound where the model was allowed to be nondeterministic.
Available in 2-4 weeks. Open to contract or full-time.
A passionate problem solver with over fifteen years of experience, currently a founding engineer at a self-funded startup building a design and prototyping tool. Before that, I worked mainly as a full-stack engineer at SaaS companies.
Problem solving for me does not stop at the product/code, I'm always finding ways to improve the development process or help colleagues get unstuck by mentoring and coaching. Also I'm not afraid to learn a new programming language/framework or to dive into the infrastructure.
Are you looking for a seasoned, product-oriented software engineer who cares about user experience and can drive a feature from idea to implementation?
I've been working for equity and now I'm looking for a full-time, long-term remote role that pays. Preferably with a SaaS company working in European time zones (CET/CEST +/- 2 hours).
Domain expertise:
- Academic: PhD in mathematics (topological data analysis, representation theory), MSc finance, MSc neuroscience.
- Applied: database proxies/networking, quant dev and backtesting engines, ML/DL for banking & finance (risk/fraud), LLMs and agentic frameworks (tools, planning, eval), image processing, audio processing.

I started working with AI back in 2014 and consider myself one of the early vibe coders. I’m interested in everything related to AI and security, I’ve worked on benchmarks, optimizations, training and inference, tinygrad, H100, B200, DeepSeek etc. I also developed an ultra-fast programming language for executing complex GPU workloads and created a generative OS for it.
Under 25, I created the core of a security scanner and built a hacking team at a UK startup ($7M investment). We removed the GIL from Python to run 30,000 threads and scan 18,000 exchange IPs for malware overnight.
I have many achievements, I created a Top-10 music app on the App Store and an Instagram filter editor for a social network that had 28,000 users at launch.
I am a Software Engineer with 5 years of experience building secure, maintainable, and data-driven web applications. I specialize in full-stack architecture, migrating complex legacy processes (like unmanaged Excel data) into modern relational PostgreSQL schemas, and integrating AI workflows.
Highlights:
- Architected a Rails 8 application migrating legacy Excel datasets into PostgreSQL with real-time visualizations.
- Integrated Gemini AI to automate i18n tasks and extract medical data from uploaded images.
- Implemented robust authentication systems including OmniAuth integration for Google, GitHub, and LINE.

24 years in infrastructure, currently Lead Platform Engineer at a security AI startup where I built the platform team from scratch (0 to 5 engineers) and architected multi-tenant Kubernetes infrastructure across 40+ clusters with per-tenant KMS encryption and Argo-based progressive delivery.
Before that, spent nearly 6 years as Staff SRE at Iterable where most of my work centered on making infrastructure cheaper and more reliable. Replaced ELK with Quickwit for 65TB/day log ingestion (saved $1.2M/year), migrated Lambda pipelines to Vector ($60k/mo down to $8k/mo), and stood up VictoriaMetrics to replace Datadog for 33M metrics ($30k/mo savings). I tend to find the project that saves the most money and then actually build it.
I write Go -- built Kubernetes operators for RabbitMQ, Redis, and Vector (open source: github.com/zcentric/vector-operator). Terraform is my IaC of choice and I've used it everywhere from a global Predix platform (Japan, EU regions) to scaling Kubernetes clusters from 10 to 300 nodes on spot instances for satellite image processing at Urthecast.
I've managed teams at three companies (up to 6 engineers) and served as product owner for SRE groups, but I'm open to both IC and management roles at the Staff/Principal/Director level.
Looking for: DevOps, SRE, Platform Engineering, or Cloud Infrastructure roles. $200K+ total comp. Remote only, US-based.
I’m Brendan, a SaaS product designer with 9+ years of experience and a B.A. in Interaction Design.
I help startups and SaaS teams turn complex ideas, unclear requirements, and inconsistent interfaces into intuitive, buildable product experiences.
Available for ongoing remote design partnerships, including product strategy, AI & SaaS UX/UI design, prototypes, design systems, and implementation-ready work.
What I do: I build agentic systems and full-stack infrastructure.
Recent work:
- Founding contributor at NimbleBrain: designed the agentic loop and workflow engine that guides AI agents through building and publishing MCP server integrations end-to-end
- Co-created Vispyr: self-hosted observability platform on AWS with automated infra provisioning, OTel instrumentation, and a full Grafana telemetry stack
- Mozilla Firefox contributor: accessibility and DevTools CSS refactors
Profile: I'm a Canadian citizen Full-Stack SWE co-creator of Vispyr, an end-to-end, self-hosted, observability tool with automated infrastructure deployment, contributor to Mozilla Firefox, and a founding contributor to NimbleBrain.
Senior full-stack Rails engineer, 9 years commercial. I ship AI features into
production SaaS — not demos.
Most recent: Review Copilot, an AI review-analytics app live on the Shopify App
Store, built and shipped solo end to end. Rails 8 backend, plus a DistilBERT
multi-label classifier I fine-tuned via knowledge distillation and serve from a
Python/FastAPI microservice, orchestrated through Sidekiq. Every recommendation
cites the reviews behind it, with a verification pass that flags claims the
underlying feedback doesn't support.
Before that: an AI-driven ABM platform (Rails + React) with LLM content-generation
pipelines, marketplace products with payments and geolocation, and a legacy
CoffeeScript → Turbo Frames migration.
Looking for senior IC work on a Rails product — ideally somewhere LLM or ML
features are on the roadmap rather than bolted on.
Backend and cloud-native platform engineer with 5+ years of experience building production APIs, distributed systems, Kubernetes platforms and Infrastructure as Code. I've built REST services in Django and Go, designed a Kubernetes-native workflow orchestration platform used by U.S. National Laboratories for predictive national critical infrastructure analysis, developed custom Kubernetes Operators and automated cloud infrastructure on AWS using Terraform, Docker, Helm and GitLab CI/CD. I enjoy solving backend and platform problems, designing APIs, building developer tooling, automating deployments and approaching development with a test first mentality. Lately I've been focused on Go, Kubernetes internals, observability and the intersection of platform engineering and AI infrastructure.

Developer with 26 years of experience who's just been told he can't progress because he's "indispensable" in his current role. I'm looking for a role as a team lead or similar, a career path beyond individual contributor. Deep knowledge and experience with many tech stacks.
Hello! I'm Rachel, a Full-Stack Software Engineer with multiple years of experience in JavaScript, TypeScript, Ruby, and Python. I recently co-created Pendulum (https://www.pendulum-baas.dev/), a reactive Backend-as-a-Service for web applications. I also recently did freelance work incorporating AI agents into Intelliflo Office for a wealth management firm, and am looking for my next permanent role.
I founded a real estate development+proptech company, exited an 8-figure gdv residential project and recently sold a decision-support saas for new-development underwriting.
Before that, I did ML research (session-based recsys, re-reranking, model selection optimization), product management at an early-stage vc, and built other end-to-end full-stack AI products that helped real estate brokerages and developers automate more than 150 hours per month in manual research and analysis workflows, more than doubling their project throughput.

Seeking: Backend/Platform/Fullstack Engineering roles, no preference in size of org
I started as a fullstack JS engineer and grew into product development at my last company. I owned the ingestion layer - collecting 100k relevant messages/month from 4 platforms through a dirt-cheap serverless back-end on Cloudflare Workers.
We worked with LLMs deeply, especially in code generation. I was part of a small team developing SpecGEM, a fine-tuned model that generates Cloudflare Workers code from JSDoc comments and is designed to outperform mainstream LLMs at this narrow task.
I just released an open-source self-hosted LLM assistant on Cloudflare Workers that predictably compounds context across conversations. https://github.com/kol3x/pawmc
Looking for a remote role where I can own work end-to-end. Stack-wise I'm strongest on Cloudflare Workers, JavaScript, and practical LLM integration.
Expert backend developer primarily focused on data engineering, mission critical/low latency/highly available systems, and AWS (certs: https://www.credly.com/users/jon-north.ad78f0c8). Happy to deal with greenfield or legacy or any mix of the two. I learn new things extremely quickly.
I prefer long term contract work, though I’ll help you with smaller things as well. W2 employment is a possibility if the fit is right. Whatever you’re doing with AI is also fine by me, and I’ll lead/adapt as appropriate.

Full-stack engineer, 8 years, front-end deep, CET. I take over live systems and restructure them without stopping the roadmap. At Jebbit (L'Oreal, AutoZone, NFL, ~1M sessions/hour) I led a four-month refactor that replaced a per-row style override system with one merged JSON schema, backwards compatible with both running in parallel. Currently on a consumer AI product where I own features end to end and took page load from 3s to 1.5s and a deep component from ~300 re-renders to ~10.
AI-native: I don't hand-write much anymore, I spec work and drive agents against it, and spend my time on judgment and review. Claude Code and Cursor daily.
16 years shipping production systems across startups and enterprises, including 2.5 years onsite at US enterprises ADP and Time Warner Cable. I build agentic AI systems that run in production daily and full-stack platforms that serve thousands of users at scale.
What I've shipped:
1. Multi-agent feature development system on LangGraph, runs daily in production. Supervised agent team, Postgres checkpointing, pgvector RAG, custom MCP servers, LangSmith eval harness, human approval gates.
I'm Ben Trettel, an experienced mechanical engineer with a PhD, specializing in computational fluid dynamics, design optimization, and verification & validation of computer simulations.

Senior software engineer, experienced with backend engineering, databases, data analytics, application security, web applications, and fullstack development.
Final-year CS student and backend developer with a systems-programming leaning. I like working with backend systems, More than that I am eager to learn from anyone. Apart from my coursework I have worked on - crawlers, TUIs and rate-limited APIs.
Open source / recent work:
Contributing to the Linux kernel - submitted patches to drivers/staging/rtl8723bs/ (checkpatch cleanups), currently working through review feedback with the maintainers.
Built web_weaver, an async Rust web crawler from scratch: tokio-based concurrency, per-domain rate limiting, robots.txt compliance, SQLite + FTS5 storage, crawl resumption via a persistent queue. First of a planned three-part research/search tool.
Comfortable across the backend stack: Go and Rust for services, Postgres/Mongo for storage, some exposure to Elixir and Zig.
Based in India (IST), but can shift my hours to get a solid 3-4hr overlap with EU or US mornings - happy to discuss specifics.
Looking for a remote backend or systems-adjacent role at an established company or a startup with real funding/traction/team - not a pre-idea-stage solo founder project or a "let's see if this works" 3-month gig. Open to relocating for the right role if the company is based in India. Happy to do a proper interview process; if you're reaching out, a link to your company/product and team size is appreciated so we can both save time.
• semantic video search using multimodal embeddings
• multi-agent systems integrating LLMs with internal data, docs, and APIs
Experience helping teams move LLM / agent workflows (incl. LangGraph/Chain) from prototype >> production.
Previously founded and exited a SaaS company serving Fortune 500 brands (pricing intelligence & channel compliance), built and led distributed team of 100+.
Full-stack engineer with 20+ years of experience, looking for a founding or first-engineer role. I build products from scratch and can work across frontend, backend, mobile, and infrastructure.
Particularly interested in small teams where I can take ownership and ship complete products.
Based in Georgia and accustomed to working US Pacific hours.
I’ve spent about half my time in first/founding engineer roles at startups, and half working directly for clients, agencies, and institutions on a wide variety of products. Folks enjoy my enthusiasm for their ideas and my ability to meet them where they are technically, always providing that extra context that builds trust and understanding.
I’m comfortable owning concerns end-to-end, from initial scoping and architectural tradeoffs through deployment of functional prototypes and user testing. I enjoy iterating and scaling systems from there, while building teams to maintain and build upon them.
Expertise in database design, media rendering systems, engagement platforms, high-volume event ingestion, ML pipelines, and getting it all working in AWS. Top priorities are data integrity, security, and privacy.
Lean on me for:
- Technical scoping and planning for a new product or platform before committing resources
- Architectural review and data modeling to see how a system should flow and which tradeoffs matter
- Greenfield builds where you need someone to plan and ship v1 without much hand-holding
- Forward-deployed engineering, working directly with potential customers to help guide the product
Pragmatic about LLMs: effective for exploration, debugging, documentation, and tightly scoped implementation work when paired with strong engineering judgment and rigid testing.
DevOps Engineer with 4 years of experience in the field and 10 years of linux administration.
Looking for DevOps/SRE/System Administration work.
Interested in multinational corporations to get myself involed in high risk/reward situations, but smaller teams are completely fine as well.
Heya, I am a developer with 4+ years of experience working with React, Next.js and node.js. I have written some blogs about things I built.

Senior Ruby/Rails engineer, 11+ years. My specialty is data-heavy Rails: making it fast, and making it correct.
- Partitioned PostgreSQL at scale — ~330M rows / ~220GB in production, entity resolution and duplicate-merging across 100M+ row tables
- Query performance — 5–40x speedups by restructuring schemas and moving hot paths off Postgres onto OpenSearch
- Billing engines — rebuilt one for ~10x faster calculation and ~50% smaller database (ActiveRecord→ROM), another for a 5x speedup on the bill pipeline
- Recently — pgvector/RAG inside Postgres, LLM integration in Rails (RubyLLM, MCP tooling)
Likely a good fit if you have a Rails app outgrowing its database, a billing or usage-metering system that's slow or subtly wrong, or you want RAG without bolting on a separate vector DB.
Open to full-time or contract. 4+ hours of daily overlap with US East now; the Lisbon move in November adds 2 more. I invoice through a registered sole proprietorship with a W-8BEN on file — no US withholding under the treaty, nothing for a finance team to set up.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
Remote: Yes, remote only. Async-preferred.

Open to both short/long-term contract or a full-time position if the chemistry is there.
I fluctuate between:
- Deep learning / Neural networks - from architecture to inference. You might have used my ♥ Lovely Tensors library if you work with PyTorch (or JAX). Some CUDA, pytorch profiler, etc.
I built and operate a 106k+ LOC production SaaS on Next.js 15, Supabase and Stripe — solo. Zero "any" types in the whole codebase, 743 passing tests.
What I'm actually good at is the part that breaks after launch: the webhook replay, the downgrade that never revokes access, the export gated only in the browser, the URL fetch that can reach your metadata endpoint. I've put my own codebase through repeated adversarial audits and can share a redacted report — real findings, real severities, subject anonymised.
Available ~20-30 hrs/week, UTC+0 — good overlap with European hours and US mornings. Contract or fixed-scope. I also do fixed-price pre-launch audits (security, billing correctness, data exposure) if that's more useful than hourly.
WHAT: Whether human or AI built, I know how systems break. I build them so they don't. After three decades of battle-tested experience there isn't a failure mode I don't know how to fix. When it comes to AI, I design and architect systems using my own rigorous engineering approach that insures consistent delivery and drift control.

** Custom architecture & development for startups and specialised cloud models
I work with companies and teams who honestly want to deliver the best product they can. I'm serious about my work and I work only with equally serious people. If you want systems built right the first time, I'm your guy.
Software Engineer with 3+ years of experience building frontend applications, backend services, automated testing pipelines, and AI-powered developer tools.
At my current company, I've improved Angular applications, built Spring Boot microservices with 100% unit test coverage, automated Playwright regression testing (reducing execution time from 2 hours to 30 minutes), and developed an AI-powered MCP server that generates Playwright tests from natural language, reducing test authoring from 45 minutes to under 2 minutes per spec.
I enjoy building products end-to-end rather than working on isolated tickets. Recently I've been focused on AI developer tooling, RAG pipelines, MCP servers, and LLM-powered automation alongside traditional backend development.
Some highlights:
• Spring Boot microservices and REST APIs
• Angular, React, Next.js, Node.js
• AI Agents, MCP, RAG pipelines, vector databases
• Playwright automation and developer productivity tools
• AWS, CI/CD, SQL
I'm looking for a remote backend, full-stack, or AI engineering role where I can own features, work closely with a product team, and build software that ships to users. Startups and product companies are especially interesting.
If you're looking for an engineer who enjoys solving problems, automating repetitive work, and shipping production-ready software, I'd love to talk.
Location: Los Angeles, CA Remote: Yes Willing to relocate: No (open to travel) Fractional / advisory: Fractional CTO or CISO, or vCISO. Open to interim and part-time engagements.
Technology and security leader, first engineer to CTO and CISO over 8+ years at a healthcare ePRO startup. Built the platform from the first line of code to a secure, audited system serving ~100K users at 99.9% uptime. Led ISO 27001:2022 certification from scratch in 6 months with zero major nonconformities. Clean record: zero security incidents, 100% audit pass rate across HIPAA, GDPR, and FDA 21 CFR Part 11. Hired and led a 10-person eng team. Cut infra cost ~66% via an AWS to OCI migration.
Good fit if you need someone to stand up a security and compliance program, get audit-ready to unlock regulated or enterprise deals, or provide senior engineering leadership without a full-time hire.

Ava, a real-time captioning platform for one-on-one and group conversations, online and in person. 11+ years, zero to product. I co-founded it and was CTO, but the backend was mine throughout, first building it and later as Backend Lead. What that covered: the live captioning pipeline, where latency, accuracy, and reliability all had to hold at once. Drove the backend from a monolith into a monolith plus microservices plus serverless, over an event-driven layer, to keep service stable. An observability stack with Prometheus and Grafana, built from scratch. A datastore migration across 100K+ accounts with no downtime, running both databases live instead of taking a batch window. The subscription and enterprise licensing backend behind customers like Disney and Nike. Penetration test remediation three years running across four teams. On call for all of it. None of this was a fresh start. Everything was already running, with real users on it, and it had to keep running while I changed it.
How I work: most of what I've built started as a vague idea, and my job was making it specific enough for other teams to build against. I own my scope end to end, and once people start building, the spec always changes. That back-and-forth is where the design actually gets figured out.
Two projects I'm working on now:
Clearway: audits websites for accessibility and drafts the compliance report a specialist would write by hand. False alarms 43% to 23%, real issues caught 74% to 83%. My first AI reviewer scored well on my own gold set and near zero on the external W3C one, because it shared a rubric with the drafter. A second reviewer reading independently now catches 53% of those errors. Small-sample measurements, not proof.
VOX Personalis: fine-tuned Whisper with LoRA on my own Deaf-accented speech, because no off-the-shelf ASR handles it. WER 238.69% to 34.05%, now with sub-second streaming output. Next is sub-20% and on-device.
Communication style: I'm Deaf and work best with text-first collaboration, clear written specs, async updates, and captions/transcripts for meetings. This is how I've worked for 11 years, including with enterprise customers.
Looking for: Senior Backend IC, MTS, or Founding Engineer scoped to backend and agent infrastructure. Seed to Series B, applied AI, SF onsite or hybrid, full-time. Going deeper, not wider. I want to put a deep backend foundation to work on the part that’s hard: making a service reliable on top of an LLM that isn’t deterministic.
Technologies: C, C++, Java, JavaScript/TypeScript, Ruby, Python, Lisp (if I can get it), PostgreSQL, Kafka, AWS, Docker, AI integration (esp. MCP)

I'm Jeff, an experienced developer with pretty broad experience. I've done things like robotics control software and video processing software, all the way up to scalable enterprise applications and big-data ETL automation. In my free time I write games, language runtimes, and hack the NetBSD kernel for fun. I freakin' love to program, and I love crafting straightforward, effective solutions that serve the user.
I build data pipelines that know when they're lying to you.
GAScout (https://gascout.pages.dev) — Georgia public-records pipeline. Four counties live, each a different ingestion problem resolved into one schema: a 9,915-page fixed-width mainframe PDF (409,142 records, zero dropped rows), a weekly XLSX roll, monthly text PDFs, and scanned sheriff's levy documents via OCR. Adding a county is a config file, not code. The other 155 are labeled planned rather than filled with invented numbers.
FindStorage (https://findstorage.pages.dev) — national self-storage pricing tracker. 4,639 locations, 245,000+ price changes logged, running unattended on a daily schedule. Aborts rather than publishing when the store count moves more than it should, because the failure that costs you isn't a crash — it's a scraper quietly returning less after a site changes and nobody noticing for three weeks.
Also built a WiFi CSI device-fingerprinting array on ESP32 — custom ESP-IDF firmware and a Python DSP pipeline, running as my apartment's security system. Cross-manufacturer separation holds at 11-15 sigma; same-model discrimination tops out near 77% and true clock twins are the open problem.
Before this I ran a 500-acre motocross park in Northern California: acquired dormant land, re-entitled it, directed a 120-person race-day crew, ran the medical plan through a mid-event helicopter evacuation, and sold my stake.
Self-taught, ~18 months in. Interested in data engineering, pipeline work, and anything where messy real-world sources have to become trustworthy structured data.
I build the systems plumbing, concurrent pipelines, and secure runtime isolation that AI coding-agent startups are racing to ship. Happy to prove it directly on your codebase first — I'll take on a 2-3 week paid trial sprint on a real backend bottleneck before any longer-term conversation.
• AutoPatch-AI (https://github.com/sriramvarun0636/AutoPatch-AI): Autonomous, self-healing code remediation agent built on a LangGraph state machine. Engineered a zero-trust Docker execution layer (network_disabled=True, 256 MB RAM / 128 PID cgroup hard limits), streamed real-time telemetry over thread-safe queues via SSE, and built an AST-based line-level parser (cutting context/generation bloat by ~80%). Achieved a 100% resolution rate (5/5) on a custom Micro-SWE-bench harness with an average time-to-resolution of ~205 seconds.
• SentinelPrime (https://github.com/sriramvarun0636/SentinelPrime): Multi-threaded, regime-aware options trading system for live WebSocket market data. Releases the CPython GIL during numerical computations using Numba JIT compilation (nogil=True) and an Actor Model architecture over daemon threads to isolate DB I/O and API calls. Built thread-safe O(1) queues and fixed-size circular memory buffers to eliminate allocation overhead under 24/7 continuous operation.
• HydraPrime (https://github.com/sriramvarun0636/HydraPrime): Systematic XAUUSD strategy in MQL5 (C++ derivative), developed and iterated solo over two years — OTE/Fair-Value-Gap structural entries with ATR-adaptive sizing and multi-layered drawdown circuit breakers. Backtested across 96M+ real ticks over a single two-year window (2024–2026) that included a strong gold bull run: 1.37 profit factor, 13.8% max drawdown, 252% net return. Not yet forward-tested live, so I hold that return number loosely until it survives a different regime.
What I'm looking for:
Backend/infra/agent-systems roles at early-stage teams, pre-seed to Series A — founding engineer or engineer #2–5, wherever you're at. Standard interview loops work fine too, not just trial sprints.
I am a software developer and researcher with half a decade of experience and a Master's degree in mathematics. I have ample experience with Golang in a professional context often on backend services like REST APIs and programs interacting with databases and message queues, am fairly proficient with a variety of other languages and technologies, and am comfortable working on a variety of domains, from accounting/financial management/CRM software, to IaaS products, to scientific and mathematical software and language apps. I enjoy learning, and am always open to learning new things, especially if they happen to ignite my curiosity.
I like free or open-source software, systems programming, web services and the infrastructure required to run them at scale and would love an opportunity to continue to contribute to and learn about them. I enjoy mathematics and quantitative research like biology, engineering and physics. I enjoy writing, and in particular writing documentation for software, educational content, and research.
I am happiest working with people who are open-minded, conscientious and kind, and I try very hard to always embody those qualities.
I am open to both full-time employment and contract work.
I am a French citizen and can work freely anywhere within the EU.
Compensation for in person work is location-dependent, and more expensive than full-remote work, due to the extra work involved (physical, moving things around in meatspace work, not just pushing bits around cyberspace). That said, I do really enjoy being in nice offices and hanging out with the team while working, and also really enjoy occasional "team in-person meetups" even when working in a full-remote context.
- Desktop, embedded, web, backend, some mobile (mostly iOS)
- Burn, GGML, NumPy, some JAX, some Mojo, some MLX
Rust is definitely my favorite and TypeScript is up there as well.
At my last company, I worked on developer experience and performance optimization. The one before that on user experience and polish. I work best on storms of small things, tend to get wrapped up on big projects.
I am fully self-taught, have been doing this for over 10 years & have a beefy personal machine (macOS or Windows). I have about 3 years of professional experience. I am available to interview immediately and can start immediately. Contact me with anything.

Currently in South America and planning my move back to the US once a role is secured (whether in San Francisco or another city) to avoid relocating twice.
Due to high interest in my work with recursive self-improving agents, I've shared an example repo at https://github.com/adam-s/agent-tuning. I'm always open to discussing how I optimize agents for complex, repetitive workflows.
I bring 13 years of full-stack UI development experience alongside deep expertise in browser automation and agents, which I've been engineering since 2018. This blend makes me particularly strong in QA automation engineering and complex frontend architecture.
Notable projects include custom legal document management dashboards and a drag-and-drop CRM email builder for social marketing campaigns. As a consultant and full-time engineer, I’ve led 0-to-1 product development across fintech, streaming, real estate, edtech, marketing, and media. Having worked at companies ranging from a 130-person AI organization to a scrappy 7-person team, I thrive most in fast-paced, high-ownership environments.

About: I am a Generative AI Engineer who also happens to be pretty hands-on across the full stack development. Most of my recent work has been building RAG pipelines, AI agents, and natural language search — using LangChain, LangGraph, and vector databases like Pinecone and ChromaDB — with OpenAI, Anthropic, and Gemini APIs under the hood. I care deeply about shipping GenAI features that hold up beyond the demo stage.
Beyond GenAI, I am working on the full stack — React/TypeScript on the frontend, Node.js or ASP.NET Core APIs on the backend, and AWS/Azure for infra. I like owning things end-to-end and building software that's simple and reliable.

Applied physicist and engineer, 15+ years. Put me on a messy, physical, high-consequence problem that crosses disciplines and has to ship — not demo.
Recent: 6 years at Agilent building production ML over instrument telemetry — fleet-wide failure prediction, and a RAG/LLM system for 300+ field engineers taken from prototype to production (including the confidence logic for when it answers vs. hands off to a human). Cut data-prep time 8x.
Before that I built scientific instruments from scratch — a fiber-based STED nanoscope and an OCT microscope — so I know data from the sensor up, not just after it lands in a warehouse. Earlier: DoD hardware reliability (former TS/SCI), precision timing, published detector-physics work.
Strongest where software meets the physical world: instrumentation, sensor data, ML that has to be right because being wrong has consequences. I own problems end to end, and I'll tell you when the result isn't trustworthy yet.
Open to full-time or contract. Health/medical-device mission a strong plus.

ML / AI Engineer with ~4 years building production systems across LLMs, VLMs, and computer vision. I take models from training to deployment at scale — 20K+ daily sessions, 30K+ cameras, multi-tenant production systems. Published in medical imaging; Kaggle and DrivenData medalist.

I build and run PersonaChat (personachat.chat), an AI character chat platform on Next.js and Supabase — live since 2025, built and operated solo.
Production LLM work rather than demos: streaming chat over the Vercel AI SDK; a long-term memory layer with append-only writes and invalidate/supersede semantics, idempotency keyed on source turn ID so a dropped stream never duplicates a turn; a relationship engine holding state across sessions that feeds back into generation; and the same character system running through a Discord surface, which forced the state logic out of the components into a shared layer.
I also instrument and read my own funnel in Postgres rather than guessing, and I run Claude Code daily against structured specifications rather than prompts — agents write most of the code, the spec and the review are the job.

AI-assisted Full-Stack TypeScript developer looking for a remote frontend/full-stack/implementation role.
I’m strongest at taking a loosely defined product task and pushing it all the way to a working result: codebase research, implementation, debugging, testing, deployment, and post-deploy fixes.
My main project is a production CRM built with Next.js/TypeScript/Node: authentication, per-user data isolation, projects and financial tracking, analytics, multi-currency support, an LLM assistant with persistent conversations, CI, automated tests, backups, and deployment on a Linux VPS.
I’ve also built automation/data-processing tooling for 20k+ structured records, worked with REST integrations and Bitrix24 data, and debugged real deployment issues across APIs, SMTP, builds, environment configuration, Nginx and PM2.
I use coding agents heavily, but not as a black box: I inspect the existing codebase, define the scope, review diffs, run type checks/tests/builds, reproduce bugs and verify the result manually before calling a task done.
I’m not looking for a role where “junior” means only converting Figma into components. I’d like to work close to the product and own real problems across frontend, backend, integrations, automation and internal tooling.
Open to full-time work and serious contract opportunities.

I specialize in bridging the gap between business strategy and technical execution. I work with executives, operators, and technical teams to identify high-value AI opportunities, translate ambiguous problems into scalable solutions, rapidly prototype systems, and drive adoption across teams.
My expertise includes enterprise agentic workflows, AI-native operating models, AI orchestration, workflow automation, autonomous business processes, and production AI deployment.
I'm particularly interested in helping companies rethink how work gets done — building AI-first workflows and augmenting decision-making where humans and AI collaborate effectively. I enjoy working across strategy and implementation, taking ideas from discovery through deployment, adoption, and continuous improvement.
Looking for Forward Deployed Engineering opportunities where technical excellence, customer partnership, and AI-driven organizational transformation are equally important. If that's the transformation your company needs, reach out via email.

22, self-taught. Won a $100K Meta Llama Impact Grant for Bluai and presented it at LlamaCon on 2025
Bluai (https://play.google.com/store/apps/details?id=com.bluai.app&...) is a hurricane early-warning app live on Google Play in Mexico, built offline-first because during a hurricane the network is the first thing to go. An online RAG pipeline and an on-device Llama 3.2 (ExecuTorch, NPU-accelerated) sit behind one interface, picking 1B or 3B based on device RAM, so the UI never knows which brain answered. When everything is down it falls back to Bluetooth/Wi-Fi mesh chat over a multi-hop wire protocol.

Flexible on compensation for the right team. I'm optimizing for who I'd be learning from, more than thinking in numbers.

I build LLM systems that run in production. The clearest example is live: pick a sector at https://demo.consentleads.uk and message it the way a customer would. Nothing is scripted. It runs on a free-tier ARM box behind a Cloudflare tunnel, is multi-tenant and has users, and nine scheduled jobs keep it going unattended.
If opt-out detection misses a phrase, the system keeps emailing someone who asked it to stop, and nothing crashes or alerts. So the suppression gate fails closed, and the eval fixtures cover that path and reply triage.
I also wrote claimcheck (MIT, https://github.com/visione4906/ctaio-claimcheck): give it a document and a codebase and a second agent has to prove every claim against the source with file and line citations, or the build fails. I built it after an outside review of my own writing turned up claims the code did not support.

SEEKING CONTRACT WORK - Forward deployed engineer, remote, email in profile. Location: West Coast, remote only.
I'm a forward-deployed engineer. My background is 15+ years of data science, but I focus on solving problems. I work in messy, ambiguous, regulated environments. Often at a client's site, inside their systems and their data. I excavate unmapped data, learn how the team works, and ship tools that stay in production.
Deployed and still running today: Legal clause extraction and validation; site corrosion detection and management; routing and predictive-maintenance systems that stayed in service.
I compress engineering, data, and modeling into one function, owned end to end. I show up, figure out what needs to be built, and make it work.
Tooling: ML/AI, LLMs, and the engineering around them: evals, determinism, observability, guardrails. The tech is just a tool, The hard part is knowing what to build.
If you have a messy, ambiguous problem that needs someone who can embed and ship, my email is in my profile.
EDIT: Corrosion detection so people don't think I detect rust code. (Nothing wrong with that though)

Trustworthy output from untrustworthy data. I build systems that catch what's silently wrong — a dead sensor nobody noticed, contradictory records, a garbled scan, a confidently-wrong model — so it surfaces as a flag today, not a six-month catastrophe.
I use LLMs where they earn their place (development, meaning, embeddings, plain-language access to jargon-locked data) and keep them out of decisions and the data flow, which stay deterministic and verifiable. An LLM can help you find the answer; it can't be the answer.
Senior systems engineer, multiple AI cycles of judgment on what survives the hype and where it breaks. Currently turning messy Polish legal PDFs into a correctness-checked graph — the hard part is the verification, not the AI. Previously I built a legislative-notification service that ran autonomously in production for over three years before I retired it. I've written about where AI coding agents actually fail and why verification is the real work: https://walat.eu
Best fit when: correctness matters, the data is real-world-messy, and you want someone who names what doesn't work and why.

Under 25, I created the core of a security scanner and built a hacking team at a UK startup ($7M investment). We removed the GIL from Python to run 30,000 threads and scan 18,000 exchange IPs for malware overnight.
I have many achievements, I created a Top-10 music app on the App Store and an Instagram filter editor for a social network that had 28,000 users at launch.
I worked on a top-30 AI cryptocurrency, built a next-gen version of BitChat https://news.ycombinator.com/item?id=48748439 and developed a file manager for offline backup drives: https://github.com/web3cryptowallet/drive-py

24 years in infrastructure, currently Lead Platform Engineer at a security AI startup where I built the platform team from scratch (0 to 5 engineers) and architected multi-tenant Kubernetes infrastructure across 40+ clusters with per-tenant KMS encryption and Argo-based progressive delivery.
Before that, spent nearly 6 years as Staff SRE at Iterable where most of my work centered on making infrastructure cheaper and more reliable. Replaced ELK with Quickwit for 65TB/day log ingestion (saved $1.2M/year), migrated Lambda pipelines to Vector ($60k/mo down to $8k/mo), and stood up VictoriaMetrics to replace Datadog for 33M metrics ($30k/mo savings). I tend to find the project that saves the most money and then actually build it.
I write Go -- built Kubernetes operators for RabbitMQ, Redis, and Vector (open source: github.com/zcentric/vector-operator). Terraform is my IaC of choice and I've used it everywhere from a global Predix platform (Japan, EU regions) to scaling Kubernetes clusters from 10 to 300 nodes on spot instances for satellite image processing at Urthecast.
I've managed teams at three companies (up to 6 engineers) and served as product owner for SRE groups, but I'm open to both IC and management roles at the Staff/Principal/Director level.

Senior full-stack Rails engineer, 9 years commercial. I ship AI features into production SaaS — not demos.
Most recent: Review Copilot, an AI review-analytics app live on the Shopify App Store, built and shipped solo end to end. Rails 8 backend, plus a DistilBERT multi-label classifier I fine-tuned via knowledge distillation and serve from a Python/FastAPI microservice, orchestrated through Sidekiq. Every recommendation cites the reviews behind it, with a verification pass that flags claims the underlying feedback doesn't support.
Before that: an AI-driven ABM platform (Rails + React) with LLM content-generation pipelines, marketplace products with payments and geolocation, and a legacy CoffeeScript → Turbo Frames migration.
Looking for senior IC work on a Rails product — ideally somewhere LLM or ML features are on the roadmap rather than bolted on.

I’m a senior engineer and software architect used to working with teams that are starting to strain under growth, complexity, or delivery pressure.
Over the last ~10 years I’ve been working with startups and established companies, primarily in roles where I take end-to-end technical responsibility: from system design through implementation and production operation, while remaining hands-on in delivery.
Recent work includes leading the architecture, implementation, and operational ownership of a distributed platform for venture capital workflows, as well as building and maintaining a survey fulfillment system. Both engagements included mentoring and coordinating engineers alongside delivery. More details can be found at https://robinsiep.com.
I'm currently interested in finding a more permanent role, but remain available for contract work in the meantime.

I started as a fullstack JS engineer and grew into product development at my last company. I owned the ingestion layer - collecting 100k relevant messages/month from 4 platforms through a dirt-cheap serverless back-end on Cloudflare Workers.
We worked with LLMs deeply, especially in code generation. I was part of a small team developing SpecGEM, a fine-tuned model that generates Cloudflare Workers code from JSDoc comments and is designed to outperform mainstream LLMs at this narrow task.
I just released an open-source self-hosted LLM assistant on Cloudflare Workers that predictably compounds context across conversations. https://github.com/kol3x/pawmc

I’ve spent about half my time in first/founding engineer roles at startups, and half working directly for clients, agencies, and institutions on a wide variety of products. Folks enjoy my enthusiasm for their ideas and my ability to meet them where they are technically, always providing that extra context that builds trust and understanding.
I’m comfortable owning concerns end-to-end, from initial scoping and architectural tradeoffs through deployment of functional prototypes and user testing. I enjoy iterating and scaling systems from there, while building teams to maintain and build upon them.
Expertise in database design, media rendering systems, engagement platforms, high-volume event ingestion, ML pipelines, and getting it all working in AWS. Top priorities are data integrity, security, and privacy.
Lean on me for:
- Technical scoping and planning for a new product or platform before committing resources
- Architectural review and data modeling to see how a system should flow and which tradeoffs matter
- Greenfield builds where you need someone to plan and ship v1 without much hand-holding
- Forward-deployed engineering, working directly with potential customers to help guide the product
Pragmatic about LLMs: effective for exploration, debugging, documentation, and tightly scoped implementation work when paired with strong engineering judgment and rigid testing.

Senior Ruby/Rails engineer, 11+ years. My specialty is data-heavy Rails: making it fast, and making it correct.
- Partitioned PostgreSQL at scale — ~330M rows / ~220GB in production, entity resolution and duplicate-merging across 100M+ row tables - Query performance — 5–40x speedups by restructuring schemas and moving hot paths off Postgres onto OpenSearch - Billing engines — rebuilt one for ~10x faster calculation and ~50% smaller database (ActiveRecord→ROM), another for a 5x speedup on the bill pipeline - Recently — pgvector/RAG inside Postgres, LLM integration in Rails (RubyLLM, MCP tooling)
Likely a good fit if you have a Rails app outgrowing its database, a billing or usage-metering system that's slow or subtly wrong, or you want RAG without bolting on a separate vector DB.
Open to full-time or contract. 4+ hours of daily overlap with US East now; the Lisbon move in November adds 2 more. I invoice through a registered sole proprietorship with a W-8BEN on file — no US withholding under the treaty, nothing for a finance team to set up.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
Open to full time or contract.
I look forward to talking with you!

Senior Software Engineer with 7+ years of experience building scalable backend systems, AI-powered applications, and cloud-native platforms. I specialize in AI agent orchestration, distributed systems, cloud architecture, and full-stack development, with extensive experience integrating LLMs into production workflows and delivering high-performance software solutions.
I fluctuate between:
- Deep learning / Neural networks - from architecture to inference. You might have used my ♥ Lovely Tensors library if you work with PyTorch (or JAX). Some CUDA, pytorch profiler, etc.

I built and operate a 106k+ LOC production SaaS on Next.js 15, Supabase and Stripe — solo. Zero "any" types in the whole codebase, 743 passing tests.
What I'm actually good at is the part that breaks after launch: the webhook replay, the downgrade that never revokes access, the export gated only in the browser, the URL fetch that can reach your metadata endpoint. I've put my own codebase through repeated adversarial audits and can share a redacted report — real findings, real severities, subject anonymised.
Available ~20-30 hrs/week, UTC+0 — good overlap with European hours and US mornings. Contract or fixed-scope. I also do fixed-price pre-launch audits (security, billing correctness, data exposure) if that's more useful than hourly.

WHO: Technology Polymath. Agentic context & harness engineering.
WHAT: Whether human or AI built, I know how systems break. I build them so they don't. After three decades of battle-tested experience there isn't a failure mode I don't know how to fix. When it comes to AI, I design and architect systems using my own rigorous engineering approach that insures consistent delivery and drift control.
SAMPLE WORK:
I work with companies and teams who honestly want to deliver the best product they can. I'm serious about my work and I work only with equally serious people. If you want systems built right the first time, I'm your guy.Full-Stack Web Developer | Remote | EU (UTC+2)

Software Engineer with 3+ years of experience building frontend applications, backend services, automated testing pipelines, and AI-powered developer tools. At my current company, I've improved Angular applications, built Spring Boot microservices with 100% unit test coverage, automated Playwright regression testing (reducing execution time from 2 hours to 30 minutes), and developed an AI-powered MCP server that generates Playwright tests from natural language, reducing test authoring from 45 minutes to under 2 minutes per spec. I enjoy building products end-to-end rather than working on isolated tickets. Recently I've been focused on AI developer tooling, RAG pipelines, MCP servers, and LLM-powered automation alongside traditional backend development. Some highlights:
• Spring Boot microservices and REST APIs • Angular, React, Next.js, Node.js • AI Agents, MCP, RAG pipelines, vector databases • Playwright automation and developer productivity tools • AWS, CI/CD, SQL
I'm looking for a remote backend, full-stack, or AI engineering role where I can own features, work closely with a product team, and build software that ships to users. Startups and product companies are especially interesting.
If you're looking for an engineer who enjoys solving problems, automating repetitive work, and shipping production-ready software, I'd love to talk.

Ava, a real-time captioning platform for one-on-one and group conversations, online and in person. 11+ years, zero to product. I co-founded it and was CTO, but the backend was mine throughout, first building it and later as Backend Lead. What that covered: the live captioning pipeline, where latency, accuracy, and reliability all had to hold at once. Drove the backend from a monolith into a monolith plus microservices plus serverless, over an event-driven layer, to keep service stable. An observability stack with Prometheus and Grafana, built from scratch. A datastore migration across 100K+ accounts with no downtime, running both databases live instead of taking a batch window. The subscription and enterprise licensing backend behind customers like Disney and Nike. Penetration test remediation three years running across four teams. On call for all of it. None of this was a fresh start. Everything was already running, with real users on it, and it had to keep running while I changed it.
How I work: most of what I've built started as a vague idea, and my job was making it specific enough for other teams to build against. I own my scope end to end, and once people start building, the spec always changes. That back-and-forth is where the design actually gets figured out.
Two projects I'm working on now:
Clearway: audits websites for accessibility and drafts the compliance report a specialist would write by hand. False alarms 43% to 23%, real issues caught 74% to 83%. My first AI reviewer scored well on my own gold set and near zero on the external W3C one, because it shared a rubric with the drafter. A second reviewer reading independently now catches 53% of those errors. Small-sample measurements, not proof.
VOX Personalis: fine-tuned Whisper with LoRA on my own Deaf-accented speech, because no off-the-shelf ASR handles it. WER 238.69% to 34.05%, now with sub-second streaming output. Next is sub-20% and on-device.
Communication style: I'm Deaf and work best with text-first collaboration, clear written specs, async updates, and captions/transcripts for meetings. This is how I've worked for 11 years, including with enterprise customers.
Looking for: Senior Backend IC, MTS, or Founding Engineer scoped to backend and agent infrastructure. Seed to Series B, applied AI, SF onsite or hybrid, full-time. Going deeper, not wider. I want to put a deep backend foundation to work on the part that’s hard: making a service reliable on top of an LLM that isn’t deterministic.

I build data pipelines that know when they're lying to you.
GAScout (https://gascout.pages.dev) — Georgia public-records pipeline. Four counties live, each a different ingestion problem resolved into one schema: a 9,915-page fixed-width mainframe PDF (409,142 records, zero dropped rows), a weekly XLSX roll, monthly text PDFs, and scanned sheriff's levy documents via OCR. Adding a county is a config file, not code. The other 155 are labeled planned rather than filled with invented numbers.
FindStorage (https://findstorage.pages.dev) — national self-storage pricing tracker. 4,639 locations, 245,000+ price changes logged, running unattended on a daily schedule. Aborts rather than publishing when the store count moves more than it should, because the failure that costs you isn't a crash — it's a scraper quietly returning less after a site changes and nobody noticing for three weeks.
Also built a WiFi CSI device-fingerprinting array on ESP32 — custom ESP-IDF firmware and a Python DSP pipeline, running as my apartment's security system. Cross-manufacturer separation holds at 11-15 sigma; same-model discrimination tops out near 77% and true clock twins are the open problem.
Before this I ran a 500-acre motocross park in Northern California: acquired dormant land, re-entitled it, directed a 120-person race-day crew, ran the medical plan through a mid-event helicopter evacuation, and sold my stake.
Self-taught, ~18 months in. Interested in data engineering, pipeline work, and anything where messy real-world sources have to become trustworthy structured data.

I build the systems plumbing, concurrent pipelines, and secure runtime isolation that AI coding-agent startups are racing to ship. Happy to prove it directly on your codebase first — I'll take on a 2-3 week paid trial sprint on a real backend bottleneck before any longer-term conversation.
Computer Science Engineer (MNNIT Allahabad). Formerly Software Engineering Intern @ DeeveloX (preprocessed 5GB+ vector search datasets with Gemini APIs).
Recent High-Agency Projects:
• AutoPatch-AI (https://github.com/sriramvarun0636/AutoPatch-AI): Autonomous, self-healing code remediation agent built on a LangGraph state machine. Engineered a zero-trust Docker execution layer (network_disabled=True, 256 MB RAM / 128 PID cgroup hard limits), streamed real-time telemetry over thread-safe queues via SSE, and built an AST-based line-level parser (cutting context/generation bloat by ~80%). Achieved a 100% resolution rate (5/5) on a custom Micro-SWE-bench harness with an average time-to-resolution of ~205 seconds.
• SentinelPrime (https://github.com/sriramvarun0636/SentinelPrime): Multi-threaded, regime-aware options trading system for live WebSocket market data. Releases the CPython GIL during numerical computations using Numba JIT compilation (nogil=True) and an Actor Model architecture over daemon threads to isolate DB I/O and API calls. Built thread-safe O(1) queues and fixed-size circular memory buffers to eliminate allocation overhead under 24/7 continuous operation.
• HydraPrime (https://github.com/sriramvarun0636/HydraPrime): Systematic XAUUSD strategy in MQL5 (C++ derivative), developed and iterated solo over two years — OTE/Fair-Value-Gap structural entries with ATR-adaptive sizing and multi-layered drawdown circuit breakers. Backtested across 96M+ real ticks over a single two-year window (2024–2026) that included a strong gold bull run: 1.37 profit factor, 13.8% max drawdown, 252% net return. Not yet forward-tested live, so I hold that return number loosely until it survives a different regime.
What I'm looking for: Backend/infra/agent-systems roles at early-stage teams, pre-seed to Series A — founding engineer or engineer #2–5, wherever you're at. Standard interview loops work fine too, not just trial sprints.

I am a software developer and researcher with half a decade of experience and a Master's degree in mathematics. I have ample experience with Golang in a professional context often on backend services like REST APIs and programs interacting with databases and message queues, am fairly proficient with a variety of other languages and technologies, and am comfortable working on a variety of domains, from accounting/financial management/CRM software, to IaaS products, to scientific and mathematical software and language apps. I enjoy learning, and am always open to learning new things, especially if they happen to ignite my curiosity.
I like free or open-source software, systems programming, web services and the infrastructure required to run them at scale and would love an opportunity to continue to contribute to and learn about them. I enjoy mathematics and quantitative research like biology, engineering and physics. I enjoy writing, and in particular writing documentation for software, educational content, and research.
I am happiest working with people who are open-minded, conscientious and kind, and I try very hard to always embody those qualities.
I am open to both full-time employment and contract work. I am a French citizen and can work freely anywhere within the EU.
Compensation for in person work is location-dependent, and more expensive than full-remote work, due to the extra work involved (physical, moving things around in meatspace work, not just pushing bits around cyberspace). That said, I do really enjoy being in nice offices and hanging out with the team while working, and also really enjoy occasional "team in-person meetups" even when working in a full-remote context.
