Proximity

We engineered a scalable event-driven architecture using message queues to ingest high-frequency GPS telemetry from thousands of trackers simultaneously. The backend processes geofence calculations and anomaly detection in real-time, pushing alerts to users within seconds of an event. The mobile application uses WebSocket connections for live map updates and falls back to polling when connectivity is limited. A custom device management layer handles firmware updates OTA, battery status monitoring, and connection health tracking. The system was designed for graceful degradation — devices buffer location data locally when cellular connectivity drops and batch-upload when reconnected.
