What I'm looking for

I'm seeking a long-term full-stack development role in France, Northern Europe, or Eastern Europe where I can build products from scratch, contribute to architecture, and take technical ownership.

At Tesseract, I maintain and develop features for the core application and co-built its automated payment and billing system end-to-end using Angular, .NET, PostgreSQL, and Docker.

Alongside my work-study program at École 42 Le Havre, I lead the technical development of VyNi, a B2C bicycle repair platform, making architecture decisions and guiding a four-person development team through its pre-launch user-access phase.

I also build products from scratch, including Bookiner, a used-book marketplace with reader recommendations, and previously created a browser-based 3D exhibition game for Normandie Impressionniste.
