Who am I ?

I’m Patric — an engineer who loves building things that work, then making sure they keep working.

My path started in Douala and ran through a Computer Engineering degree at ENSPY before bringing me to France. Over the last six years I’ve worked both sides of the craft: shipping end-to-end web apps with TypeScript, React and Next.js, and building the automated frameworks — API, web and mobile — that keep them honest in production.

What I really enjoy is the whole loop, from a developer’s commit to a confident release. I’ve learned that good testing isn’t a gate at the end — it’s what lets a team move fast without holding its breath, and it has quietly shaped how I think about building software in the first place.

Away from the day job I’m usually tinkering with something — an API-mocking CLI, a small RAG platform, whatever idea is keeping me curious that week. I care about clarity and reliability, and I do my best work in teams where quality genuinely matters.
