Android engineer in Fürth, Germany. I work on system apps in Android Automotive OS. Before that I worked on the Kinegram Mobile Chip SDK, Android and iOS libraries that verify electronic passports over NFC.
In my own time I build party games where phones are the controllers and a shared screen is the display:
- Paper Balloon Controller: the controller app, Jetpack Compose on Android and SwiftUI on iOS. App Store
- Tiny Track Party: kart racer with one C++ engine for the browser, Android TV and Apple TV. tinytrack.paperballoon.games
- HexStacker Party: party game for one to eight players in the browser, also on Apple TV. hexstacker.com
- Party-Sockets: the WebSocket relay server behind them.
Upstream contributions:
- zxing-cpp: #1151 and #1152 roughly halved the size of the Android library.
- Google Filament: tvOS support, Metal GPU timer queries, Vulkan pipeline cache, Vulkan readPixels, iOS backend tests.
