Backend Developer Needed for GPS OBD Tracking Gateway
Budget: $30 – $250 USD
I need a backend developer to build a new GPS OBD tracking gateway service.
The service must communicate with GPS OBD devices using the protocol document I will provide. The developer must read and follow the attached GPS OBD scanner protocol file to build the system correctly.
This is a new project. There is no existing codebase to fix.
What I Need Built
The backend should:
Accept TCP connections from GPS OBD devices
Decode GPS OBD / JT/T 808 protocol messages
Handle device registration
Handle device authentication
Process heartbeat messages
Receive and save GPS location data
Receive and save OBD vehicle data
Process alarms and fault code data
Send commands from the server to the device
Store all important data in a database
Include logs, error handling, and setup instructions
Deliverables
The final delivery should include:
Complete source code
Database schema
Working TCP gateway server
Device message decoder/encoder
Command sending feature
Installation instructions
Simple explanation of how the system works
All communication must stay inside Freelancer.
