About

I am already building under real constraints.

Useful products, sharp interfaces, backends that hold. Learning by shipping.

Same reflex since the start: learn fast, ship something concrete, fix the weak parts, repeat.

Epitech Paris on one side, a company on the other. At Vibaura I lead the tech: API contracts, the Flutter app, the deployment path.

Product-minded

Usefulness first. Every feature has to earn its place.

Fullstack range

Frontend, backend, mobile, data, deployment. The whole chain.

Execution habits

Clean delivery, reusable architecture, short feedback loops.

What I chase: a clear problem, an interface that stays clean under complexity, a backend that holds when usage grows.

Current direction

Scaling Vibaura: cleaner architecture, stronger mobile flows, backend choices that carry real users.

Working style

Build, test, listen, then iterate on what actually moves the product.

Proof

Products that real people already pay for.

Live metrics and customer feedback from my FiveM store: delivery, support and iteration, well past school projects.

FiveM store

Real customers, real support

A Tebex store taught me delivery, support, repeat buyers and long-term maintenance.

Client trust

Feedback counts as much as shipping

Reviews are pulled in automatically: quality and follow-up are part of the work.

Projects

Products, experiments and systems I have shipped.

Featured projectCo-founder and tech lead. Live at vibaura.app.

Vibaura

A padel platform: an Elo-style ranking, strictly validated match results, a social feed and partner-ready ranking widgets. Flutter app, Next.js site and back-office, NestJS API, all typed from one OpenAPI contract.

Objective

Padel has no trusted ranking. Scores live in group chats and no level is comparable.

Result / learning

A shipped platform where I own the architecture, the contracts and the release path.
