Building a Real-Time Delivery App for 50,000 Users in UAE
A Dubai-based logistics startup needed a cross-platform delivery tracking app built in 14 weeks. We delivered a real-time React Native app that scaled to 50,000 monthly active users within 6 months of launch.
The Challenge
The client needed both a customer-facing app (track deliveries in real-time) and a driver-facing app (accept/reject orders, navigation) - for both iOS and Android - with a Node.js backend integrating Google Maps, push notifications, and a real-time WebSocket system. Timeline: 14 weeks to beta.
The Solution
We used a React Native + Expo monorepo strategy to share 85% of code between the customer and driver apps. Real-time order tracking uses Socket.IO with Redis pub/sub. The backend on Node.js + PostgreSQL handles order state machines, driver matching logic, and webhook integrations with the client's existing ERP. We implemented automated Fastlane deployments for both App Store and Play Store.

Measurable Results
"We interviewed 4 agencies before choosing DelhiStack. They were the only team that asked the right technical questions in the discovery call. They delivered early, and the app is rock solid at scale.
