With 8+ years of professional Android experience, I specialize in location-based and real-time tracking apps — GPS tracking, maps integration (Google Maps, OpenStreetMap), and Firebase-backed data sync. At my current role, I work on a multi-module driver/logistics app that handles real-time location data at scale, and I led a rework of our notification system that improved delivery reliability from 85% to 97% for 40K+ active users — critical for apps where users depend on timely location/status updates. On Upwork, I've completed a geomapping mobile project (5.0★). I also bring real-time messaging integration experience (MQTT, via Gojek's Courier SDK) — relevant for apps needing live tracking updates rather than just static map display. Core Expertise: Real-time GPS tracking & location services (background location, battery optimization) Maps integration: Google Maps SDK, OpenStreetMap Firebase (Auth, Firestore, Cloud Messaging) for data sync and notifications Multi-module Android architecture, Kotlin Coroutines & Flow Real-time messaging (MQTT) for live tracking/status updates Additional exposure: Flutter, Kotlin Multiplatform (KMM) — 1 year each
