About me

Crafting modern web
experiences that matter

Full-stack developer based in Brussels with over 3 years of professional experience. I specialize in building end-to-end web applications — from architecting backends with NestJS and PostgreSQL to crafting pixel-perfect frontends with Next.js and Svelte.

I thrive in fast-paced product teams, enjoy taking ownership of features, and care deeply about code quality, performance, and developer experience. Always looking for the next challenge.
