Software EngineerFullstackAI TinkererTechnical Co‑founder
I build software end‑to‑end : from LLM‑powered products and mobile apps to the systems that keep them running. A decade shipping for startups, scale‑ups and aerospace, plus a workshop full of hardware side‑projects.
§1GENERAL DESCRIPTION
From sysadmin at École 42 to fullstack roles, an AI/LLM stint, lead mobile work and a startup CTO seat, I've worn most of the hats a software team needs.
Off the clock I prototype flight‑controller boards and on‑board computers. The same curiosity that drives those keeps my product work sharp.
FEATURES
▪ 10+ years shipping production software
▪ LLM / AI product integration, end‑to‑end
▪ Fullstack & mobile - from PCB to UI
▪ Startup CTO - built tech & team from zero
