Cabvibe Real-Time Ride Engine

The real-time backbone of a ride-hailing app: every driver location, ride request and status change flows through this service.

The ride-hailing mobile app used Firebase for real-time updates, which cost about $300/month and was not efficient.

• A Go WebSocket server running on two instances behind a load balancer.
• Redis for shared state and pub/sub so both instances see the same rides and drivers.
• Driver assignment, live location updates and the full ride lifecycle: request → assign → pickup → trip → complete.

About 10x more efficient, and the $300/month Firebase cost was removed completely.
