Working at Built and deployed a complete multi-role food delivery platform for G-food Delivery Pvt Ltd as the sole mobile developer. The system covers every side of the business — customer ordering, restaurant order management, and live driver tracking — all connected through a shared Firebase backend. What I built: — Customer app: browsing, cart, OTP login, real-time order tracking, payment integration — Restaurant partner app: order acceptance, menu management, live status updates — Driver app: delivery assignment, live location sharing, earnings tracking — Firebase backend: Firestore, Cloud Functions, MSG91 OTP, Razorpay payments Every component was built in Flutter from the ground up — architecture, state management, backend logic, and third-party integrations. This is production software running a real business, not a side project.
