I need a vehicle-tracking solution that runs smoothly on both a dedicated mobile app (Android & iOS) and a browser-based dashboard. The core objective is straightforward: show each vehicle’s live position on an interactive map so I can monitor my fleet from anywhere. While real-time visibility is the main priority, I’m open to your suggestions on complementary functions such as route playback, geofencing alerts, maintenance reminders, or anything else you feel would add real value—I’m happy to discuss possibilities during development. Please use whichever mapping SDK, GPS hardware protocol, and backend stack you believe delivers the best balance of performance, accuracy, and maintainability; just be sure the final system is reliable and easy for me to manage in the long run. Deliverables I expect: • Mobile app (Android & iOS) with real-time map view • Web dashboard mirroring the same data and controls • Full, well-commented source code and a clear deployment guide If you have prior experience building cross-platform GPS or fleet-management tools, I’d love to see it.
