About · Boulder, Colorado
Hi, I'm Antonin.
Staff Engineer building AI-backed systems, engineering standards, and the workflows that let teams ship serious software.
20+ years building · blogging since 2012 · 600+ GitHub stars
Principles
- A deployed MVP is worth two prototyped.
- Dance like nobody is watching, code like everybody is.
- Today's fashion is tomorrow's legacy.
- Debugging becomes easier if you first admit that you are the problem.
- The best code is no code at all.
The rest of the operating system
- Photography
- I shoot animals, landscapes, people, and street scenes. The camera is how I stay observant.
- Fiction
- I write AI-themed fiction and short stories when technical writing is not enough.
- Podcasts & games
- I have opinions about Final Fantasy, narrative design, and the overlap between games and technology.
What I work with now
The stack changes. The throughline doesn't. I'm usually working where backend systems, product delivery, and AI workflows collide.
- AI & LLM systems
- Measuring model output, routing it across providers, and trusting none of it by default.
- LLM Evaluation & Judge Grading · Multi-Provider LLM Dispatch · Token Budgeting & Rate-Limit Engineering · Structured Output & Guardrails · Model Context Protocol (MCP) · Agent Tooling & Orchestration
- Languages
- Python on the backend, TypeScript for everything else, SQL wherever the data lives.
- Python · TypeScript · SQL
- Platforms & tools
- Async services on Kubernetes, databases picked per job, front ends in React or Svelte.
- FastAPI · Redis · Postgres · SQLite · Kubernetes on Azure · React & Next.js · SvelteKit
- Leadership
- Setting technical direction and standards, then reviewing what ships against them.
- Technical Strategy · Engineering Standards · Cross-Team Delivery · Code Review · Mentoring

Working together
I help teams implement AI-enabled product work, sharpen engineering practices, and build systems that survive real usage.
That's me, more or less.
The rest is in the writing.
