Summary

Profile · Positioning

Senior Android engineer with cross-stack reach — Uber Maps SDK (JNI/C++), Architecture, Jetpack Compose, and broadcast-grade streaming. Ten-plus years shipping production apps inside large engineering organisations — from Uber's 10K+ engineer global codebase (RIBs, Buck, native NDK/JNI) to greenfield Android TV and Fire OS frameworks at broadcast scale. As an independent contractor I run multiple client engagements in parallel — at any given time only one is full-time, with the rest as part-time concurrent contracts.
