What I build

Real-time video and camera

up to 20%

faster real-time video processing and export, after I optimized core effects with Metal shaders and Core Image custom kernels.

Image processing

HEIC to JPEG

offline, with a C++ HEVC codec core. When iPhone 7 launched, Luma was the only app that could convert offline.

Engineering leadership

about 25 min

builds, down from 1.5 hours, after I moved the app to a modular architecture and from CocoaPods to Swift Package Manager.

Apps

Calm puzzle games I build and publish for iPhone, iPad and Android.

Stack & Spin

Drag little 2×2 cards onto the board, spin them to fit, and stack them where the colours match.
