Mobile app developer. I build React Native apps and the native layer underneath them — Swift on iOS, Kotlin on Android.

Open source

react-native-tour-guide — onboarding spotlights and coach marks. The spotlight matches the real shape of whatever it highlights via SVG masking, with zero native dependencies.
react-native-liquid-glassmorphism — bridges UIGlassEffect on iOS, and renders hand-written AGSL refraction shaders on Android where no equivalent exists.
Design System Auditor — a Figma plugin that scores design files for AI-readiness and fixes token drift.

Working on

SnoozeWar — a sleep-wake enforcement app I built solo. Most of the interesting work lives in the Kotlin layer: exact alarms, a foreground service, accessibility-based app blocking, and on-device sleep detection.

Learning

Graphics on Android — AGSL shaders came out of the glass library and I’ve kept going. Also the parts of the platform that actively fight you: doze, background limits, and everything that decides your process shouldn’t exist.
