About

Hi there! 👋

I'm a freelance web developer and contractor based in Zürich, Switzerland.

I build performant, user-centric web applications. I develop both visually appealing apps and kick-ass architecture layers. Clients often hire me to create prototypes, products, or entire ecosystems from scratch.

My frontend skills include Svelte, Angular, React and StencilJS, though I'm particularly passionate about framework-agnostic solutions using TypeScript.

Not being a big fan of big tech fuels an interest in decentralized networks — especially the Internet Computer, on which I built Juno.

While I don't handle backend work for clients, I have developed smart contracts in Rust for my personal projects.

I hold degrees in Computer Engineering and an Executive Master’s in Business Administration (EMBA), and I’m fluent in French, German, and English.

When I'm not coding, you can find me running on mountain trails. 🏔️🏃

If you have a project in mind or need some help, get in touch!
