About me
I'm a Senior iOS Developer with over a decade in the IT industry and a Master's degree in Cryptography. My focus is the Apple ecosystem - building business applications for iPhone and iPad from the ground up, as well as evolving established products.
I've published my own apps: NetworkHelper, live on the App Store for over 9 years, and Radien, a privacy-first network toolbox for iPhone, iPad and Mac released in 2026. In recent work I've gone deep on ArcGIS maps, Combine, and Swift's async/await concurrency, with a constant eye on clean, maintainable architecture.
