GPS & Fleet Tracking Apps + Traccar Server | Flutter Developer

GPS and fleet-tracking apps that hold up in the real world: accurate live location, tracking that survives a lost signal, and background updates that don't drain the battery. Two of them are live on the App Store — EcuaGPS and SmartTrackerz — and I've delivered GPS platforms here on Upwork at 100% Job Success, including a white-label GPS system and a Flutter + Traccar tracking app. If your project involves GPS, fleet management, telematics, live location or logistics, you've found someone who has already built and launched it — not someone learning on your budget. What I build for tracking and fleet clients: • Real-time GPS tracking — live map, trip history, route playback • Geofencing with enter/exit alerts that actually fire • Traccar and custom telematics integrations • Driver behaviour, speed and idle monitoring • Fleet dashboards, driver mobile apps and admin panels • Offline-first data capture with low-latency sync • Freight and auto-transport platforms — dispatch, loads, carrier and driver portals Traccar server work, not just the app: • Production deployment on your own VPS, not a shared demo instance • Migration off the bundled H2 database to PostgreSQL, with tested restores • TLS, backups and monitoring set up properly • Custom protocol support for trackers Traccar doesn't handle out of the box I'm also strong at taking an unfinished or buggy Flutter app and getting it stable and launched. How I work: • 100% Job Success on Upwork · 4+ years · 4 live App Store apps • Weekly TestFlight / Play Console builds so you see real progress • Clear communication with daily overlap on US hours • You own the code and the repository — full handover, always Send me your project details and I'll come back with a clear plan, honest scope and a realistic timeline.
