Hi, I'm Antonin.
Staff Engineer building AI-backed systems, engineering standards, and the workflows that let teams ship serious software.
Staff engineer focused on the infrastructure production LLM systems run on: evaluation harnesses, multi-provider dispatch, rate-limit handling, and guardrails on model output.
Five fortune-cookie slips
kept in the wallet
01A deployed MVP is worth two prototyped.
02Dance like nobody is watching, code like everybody is.
03Today's fashion is tomorrow's legacy.
04Debugging becomes easier if you first admit that you are the problem.
05The 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 toolbox, labelled
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
Proof, in stubs
things you can open right now
I help teams implement AI-enabled product work, sharpen engineering practices, and build systems that survive real usage.
