Hi there! šŸ‘‹

About

I'm David, a freelance web developer based in ZĆ¼rich, available for project-based work and contract positions.

My focus is building performant web applications with careful attention to both interface quality and secure, scalable architectural foundations. Clients hire me to create prototypes, products, and complete ecosystems from the ground up.

Recent work includes large applications, developer tools, and platform ecosystems.

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

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

When I'm not coding, you can find me running on mountain trails. šŸ”ļøšŸƒ
