I've spent ten years on mobile — mostly iOS, mostly the parts other developers build on top of. I've worked on an identity-verification SDK that handles more than 25 million document scans a year across 200+ countries, and a video player SDK serving over 10 million streaming sessions a month. These days I lead a mobile team across iOS and Android and write Spring Boot services alongside it.
On my own time I make small, self-contained apps. They work offline, they don't ask for an account, and they collect nothing — partly because that's a better product, and partly because I've seen enough SDK integrations to know what "just a little analytics" turns into.
Apps
-
MeloTouch
Interactive calm — touch-driven ripples, soundscapes and breathing exercises for ADHD, anxiety and sensory regulation. On iOS and Android. Offline, ad-free, no tracking.
-
Kerflinein development
A minimalist one-tap arcade game. A dot slides along a wire, tapping flips its gravity, and every death is deterministic — and therefore yours.
Open source
-
SwiftFormBuilder
A declarative SwiftUI library for complex forms — a result-builder DSL, built-in validation, responsive layouts and customisable styling.
-
FloatingTextField
A floating-label text field for SwiftUI.
