Rider App

Booking, ride tracking, and payments for passengers across Algiers

The rider app handles the full passenger journey — from onboarding and address search to live ride tracking and payment. I built it with a modular architecture so features could scale independently as the platform grew past 100K downloads.

  • ● Server-driven onboarding flows configurable from the backend without app store releases
  • ● Real-time ride tracking with map integration and driver ETA updates
  • ● Gradual Jetpack Compose migration for smoother UI and faster iteration

Driver App

Trip management, earnings, and navigation tools for partner drivers

The driver companion app powers daily operations for ARBIN's fleet — accepting rides, navigating to pickups, and tracking earnings. Stability was critical on a wide range of Android devices used by drivers in the field.

  • ● Incoming ride requests with accept/decline and turn-by-turn navigation
  • ● Earnings dashboard and trip history for driver transparency
  • ● Background location and notification handling optimized for battery life

Key Highlights

  • ● Modular architecture for scalability across rider and driver codebases
  • ● Server-driven UI for onboarding flows — update screens without app releases
  • ● Jetpack Compose migration for modern, declarative UI on both apps
  • ● 99.68% crash-free rate through rigorous stability monitoring and fixes
  • ● 15% performance improvement through profiling, caching, and UI optimization
