About

I’m Rafał, a senior iOS engineer currently building the SRF News, Meteo, and Sport apps — the flagship mobile products of Switzerland’s national public broadcaster, serving over a million daily users.

I’ve been writing iOS apps since 2010, shipping across healthtech, cleantech, and broadcast media. My work spans the full stack when needed — I’ve owned Python and .NET backends, built CI/CD pipelines, and led rewrites of large production codebases.
