Building Scalable Rider Apps

The Latency Challenge

In ride-hailing, every millisecond counts. We engineered Carbs to handle high-concurrency requests, ensuring that when a user requests a ride, the nearest driver is matched instantly.

Using WebSocket clusters and geospatial indexing, we reduced matching latency by 40% compared to legacy solutions.

Driver Experience First

We built the driver app with offline-first capabilities and battery optimization in mind. Carbs isn't just a rider app; it's a livelihood for thousands of drivers.
