Production Android
Every application in this portfolio is live, load-tested, and operating under real user conditions. Architecture first — UI second.






The full portfolio
Native Android applications built across logistics, fintech, health, and productivity verticals. Each one passed production load testing before release.




Architecture under pressure
Sub-100ms data pipeline
A fintech client required live account balance updates across 50,000 concurrent sessions. We engineered a WebSocket layer with offline-first Room persistence, eliminating dropped state on network transitions.
GPS tracking at fleet scale
A 3,000-vehicle fleet demanded continuous GPS reporting without draining device batteries. We implemented a WorkManager-based background sync architecture with adaptive polling intervals, keeping battery impact under 3% per shift.
