Managing a real-time fleet across so many vehicles is overwhelming when each device, SIM, and route needs to stay visible and secure. Juggling offline maps, SIM balances, and airtight security—especially with no cloud reliance—can drain time and focus fast. You’ll gain a self-hosted GPS tracking system where every vehicle’s status, route, and SIM is always at your fingertips, with all data staying on your own server and strong encryption protecting every connection. First, I’ll set up the backend to receive and store live GPS data from your Valtrack V4 devices, integrating PostgreSQL and OpenStreetMap offline. Then, I’ll build a dashboard that lets you view all vehicles, manage SIMs, and get instant alerts right in Windows. Finally, I’ll connect payment integrations so you can handle bulk SIM recharges without hassle. How would you like the SIM management and recharge flow to feel for your team?

Hi, I will set up your self-hosted Traccar stack on PostgreSQL/PostGIS with OSM offline tiles, the custom fleet dashboard (map, color-coded status, playback, alerts), and the SIM recharge module with Mada/Stripe/Telr. On offline maps: full OSM tile sets run terabytes. I will clip your region and serve via TileServer GL, keeping storage and load times sensible. Questions: 1) Valtrack V4 already procured, or in scope? 2) Which region to clip for offline maps (country, city, or custom polygon)? 3) Does the budget cover prototype/pilot only, or the full system? Send me a message and we can go over the details. Best regards, Faizan

Hello, there! I can build a self-hosted GPS tracking platform around Traccar, PostgreSQL/PostGIS, offline OpenStreetMap, and a custom dashboard for fleet monitoring, alerts, playback, and SIM management. I have experience with IoT/GPS systems, backend APIs, Docker deployment, PostgreSQL, payment integrations, and secure full-stack platforms. For your setup, I would first validate the Valtrack V4 protocol and confirm data flow from one device into Traccar, then build the custom backend/dashboard layer for fleet status, route history, geofencing, reports, SIM recharge, payment history, and balance alerts. The system can run on Windows using Docker, with TLS, role-based access, database migrations, Swagger docs, and no external cloud dependency. I would approach delivery in phases: one-device prototype, 10-device pilot, then scaling and final hardening for 150 vehicles. I can also provide the hardware integration guide, deployment documentation, and ownership-ready source code. Best regards, Ian Brown
