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 app, NetworkHelper, which has been live on the App Store for over 9 years. 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.
