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. Twenty years across legal AI, creator platforms, payroll, startups, and consulting. Currently in legal AI, where a confidently wrong answer is worse than no answer.
Experience
Where I've been
Over 14 years across startups, scale-ups, and post-acquisition teams — from first engineer to staff-level technical leadership.
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.
Beyond Code
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.
Capabilities
What I work with now

Languages
Frameworks
Leadership
I help teams implement AI-enabled product work, sharpen engineering practices, and build systems that survive real usage.
