Last update, Sep 2026

A technical director of 33, I fell into code as a child. My first open-source contribution was in 2007, at 14, to get my maths homework done faster. Self-taught by temperament, I keep a constant watch on new technology.

My interests are software architecture, automation and cybersecurity.

Today marks a new step: adnap belongs to the social and solidarity economy and is a mission-driven company. Our aim is to help organisations gain autonomy and reduce their dependence on third parties.

I believe in empowering teams, betting on trust, competence and a dose of good communication.
