Overview
Production logistics app with real-time vehicle tracking, dynamic geofencing for delivery validation and zone safety, live analytics, and ObjectBox offline-first architecture for field operations.
Challenge
Dispatchers needed live vehicle positions and automatic delivery validation, but drivers routinely lost signal in the field — so naive real-time tracking dropped events and corrupted delivery records.
Solution
Shared one codebase between driver and dispatcher apps, layered dynamic geofencing for delivery/zone-safety validation on top of sub-second GPS, and used ObjectBox + Firebase sync so events survived connectivity gaps.
Key work
- Real-time GPS tracking with sub-second map updates
- Dynamic geofencing with configurable delivery zones
- Zone safety alerts and boundary violation detection
- Offline-first data sync with ObjectBox and Firebase
- Analytics dashboard with delivery metrics
- Driver app and dispatcher console on a shared codebase
