Sahand
Sahand is an enterprise ride-booking platform for Tehran Municipality — an Uber-style service with passenger apps on Android, iOS, and PWA, plus a dedicated driver app.
- Built both apps in Flutter against a Node.js backend with a SQL database.
- Implemented continuous driver location tracking that keeps reporting while the app is closed: an Android foreground service, and background location on iOS.
- Added a fallback path for dropped connections — a Firebase push notification to the driver, followed by an SMS confirmation to the passenger.
- Reached 10,000+ downloads in the first month after launch.
