Chat & live-call app
RichBengali
A cross-platform social app with real-time chat, audio/video calls and per-minute creator earnings.
The problem
Calls had to ring natively even when the app was closed, and creators needed to be paid by the minute through local payment methods.
What I built
- Flutter app with Socket.IO messaging and Agora RTC calls
- Native incoming calls: iOS CallKit + PushKit, Android ConnectionService + FCM
- Wallet, live earnings and payouts via bKash and bank transfer
- FastAPI backend on Google Cloud Run
Result
Published on Google Play after closed testing and the full policy review.
