The challenge
A ride-hailing service is two products that have to work as one. Riders want a booking that is confirmed quickly and a driver they can see approaching. Drivers want a steady flow of nearby requests and clear navigation. If either side has a poor experience, the other side feels it immediately.
Chalak needed a platform for auto and cab bookings that could onboard drivers at scale and keep riders and drivers in sync in real time.
What we built
- Rider app to book an auto or cab, see the fare, and follow the driver live on the map.
- Driver experience for going online, accepting nearby requests and navigating to pickup and drop.
- Matching that connects each request with available drivers close by.
- Onboarding and operations tools to bring new drivers onto the platform and keep the fleet running.
