I need my live B2B fintech portal (https://b2b.digifinpay.com) rebuilt as a fully-native Android application in Kotlin. The backend—PHP with MySQL—already exposes clean, well-documented REST APIs, so your focus is UI, API binding, and biometric SDK handling. Tech stack & architecture • Kotlin using MVVM or other Clean Architecture patterns • Retrofit for networking and JSON parsing • OTP + MPIN login with device binding, SSL pinning, and token-based sessions Biometric requirement AEPS transactions must trigger the RD Service intent flow for Mantra, Morpho, and Startek devices. Please demonstrate successful capture and response handling for each model during testing. Dashboard behaviour On launch the dashboard must pull data dynamically and show: 1. User account summary 2. Recent transaction history 3. Quick shortcuts to services Core modules to wire up through existing endpoints include AEPS, DMT, BBPS, Recharge, Wallet, Ledger, Flight, PAN, and Loans. I expect a lightweight UX comparable to SpiceMoney, with responsive layouts and smooth navigation throughout. Deliverables • Complete Android Studio project with readable, scalable code and clear package separation • Working APK signed for testing • Integration report confirming all API endpoints hit, SSL pinning verified, and biometric capture on the three specified devices All endpoints, request/response samples, and Postman collections are ready for you. Let me know your timeline for each milestone so we can get this into production quickly.
