The project

Turning a complex workflow into a dependable product.

Challenge

Coordinate live bookings, location-aware driver matching and multi-sided mobile workflows while keeping fare rules and branch operations maintainable.

Approach

Model the domain around explicit booking states, isolate pricing services, use Redis GEO for proximity, and keep the Rails APIs and Expo clients modular as operations evolve.

Contribution

  • Led system architecture and phased delivery
  • Built fare, location and dispatch workflows
  • Managed AWS deployment and production operations

Outcome

A dependable foundation for local ride-hailing and delivery operations with room to introduce new pricing and dispatch rules incrementally.
