I build reliable Android apps for live sports, media, and field operations.

I've built and stabilized Android products at Sixlogics, Nextbridge, NextAge Technologies, and Hashloops, including live sports apps serving 1M+ users. At Sixlogics, I brought a crisis-hit sports app's crash rate down to 0.5% and kept it there across four releases.

I ship the full mobile delivery stack: architecture, features, testing, media playback, real-time updates, offline sync, and store deployment. My work includes a custom ExoPlayer highlights player, a live Horse Racing centre, and an offline-first field operations app using Room DB and WorkManager.

I've also built SmartSchoolBus end to end with live Google Maps tracking and parent alerts, plus Flutter products for cross-platform scheduling and payments.
