About

A developer who ships.

I'm a full-stack software engineer based in Switzerland, focused on building products people actually rely on — from hospital-grade EHR systems to Web3 marketplaces and serverless SaaS platforms.

My work sits at the intersection of a clean frontend and a solid backend: TypeScript everywhere, React and Next.js on top, Node.js, NestJS, or Spring Boot underneath, deployed on AWS with CI/CD I own end-to-end — backed by real testing practice (JUnit 5, Mockito, Jest, TDD where it counts).

AI tooling is part of how I work: Claude and GitHub Copilot are in my daily loop for code review, documentation, and faster iteration — and I've learned where to lean on them and where to verify everything myself.

Off the keyboard: gym & training, music across genres, technology & open source, AC Milan.
