I build native iOS apps in Swift and SwiftUI. At work that's the mobility and ticketing apps of Hamburger Hochbahn AG (~2.5M users): ticketing and purchase flows, migrating a grown UIKit codebase to SwiftUI, and accessibility.
Most of my professional work lives in closed source. What's here is what I build and break in my own time.
Open source. I'd rather fix something upstream than work around it: 10 merged pull requests in projects like home-manager, nixpkgs, authentik and podcast-dl, plus minimal reproducible examples when I run into a library bug.
