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.

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

Beyond code

Picture 2

Interests outside of code
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.
