- GPS-based location tracking with Google Maps API.
- Spring Boot REST APIs with JWT-secured endpoints.
- MySQL backend for field data persistence.
Impact
- Gave field managers real-time visibility into team activity and visit completion.
- Delivered a polished, production-ready mobile app end-to-end.
Challenges solved
- Designing consistent UX for both Android and iOS through Expo.
- Balancing real-time GPS polling with battery and data constraints on field devices.
