Yalla Otlob – Multi-Role Delivery & Ride-Hailing App

Architected and built a multi-service platform solo — spanning food delivery, logistics, and ride-hailing — supporting 5 user roles (Admin, Restaurant, Delivery Driver, Taxi Driver, Customer) on one shared Flutter/Supabase codebase.

Designed the full database schema in Supabase, implemented authentication and real-time data sync, built live Google Maps tracking for delivery/ride routing, and set up Firebase Cloud Messaging for real-time order and ride notifications across all 5 role-based apps.
