Description

Software engineer with over 20 years of experience, I build systems where the business domain guides technical choices. My conviction: sustainable quality arises from the alignment between software architecture and business reality — an approach I embody through DDD, hexagonal architecture, and an ingrained Software Craftsmanship culture (TDD, pair programming, CI).

My background covers various contexts: a critical medical system for 5 years (Stago, team of 30), a large e-commerce platform in London (Just Eat, Trainline, FindMyPast), and a greentech startup with IoT terminals (BIBAK). This diversity has taught me to choose the right architecture for the right context. At BIBAK, I also supported the growth of a team from a few developers to 10, structured two teams, and disseminated a common technical culture.

Specializing in React / Node.js / TypeScript since 2017, with 3 years of experience as a Lead in London, I am looking for an ambitious project in Paris starting in June — within a team that values technical rigor as much as velocity.
