Food Delivery Platform
#flutter#firebase#stripe#googlemapssdk
the vision
End-to-end three-sided marketplace with real-time order tracking.
the hurdle
“The client required a scalable, three-sided marketplace (users, restaurants, drivers) capable of handling high-volume concurrent orders with sub-second real-time location tracking for deliveries. Existing boilerplate solutions were too rigid and failed under load.”
01the architecture
Built the entire mobile client suite using Flutter with Clean Architecture principles. Integrated Google Maps SDK with custom polyline drawing algorithms to show driver routes. Developed a robust state machine to handle the complex order lifecycle (placed -> accepted -> preparing -> picked up -> delivered). Payments were securely processed via Stripe with full SCA compliance.
02battle scars
Tracking drivers accurately without draining their battery was a significant hurdle. I implemented background geofencing and dynamic polling intervals that adjusted based on the driver's velocity and distance from the destination. Another challenge was ensuring real-time UI updates without race conditions, which I resolved using reactive streams (RxDart).
03the harvest
Successfully launched a production-ready marketplace that scaled to handle peak-hour traffic without downtime. The custom background location tracking improved ETA accuracy by 25% while reducing driver battery drain by 15%.
