Hello, I have a complete fintech web portal already developed, live and actively in use. All backend, admin panel, database and business logic are stable and running in production. Existing system includes: * Retailer / Distributor / Master Distributor hierarchy * Full admin panel and database * Services already working on web: * AEPS * DMT * BBPS * Flight Ticket Booking Requirement: I want to build a native Android user app to improve smartphone user experience for field users. Scope of Android App: * 100% native Android app in Kotlin * App will consume existing APIs * No backend work * No admin panel * Login via mobile number + OTP * User dashboard and services screens * Transaction flow, history and profile * AEPS biometric integration via RD Service * App architecture should support future face-auth module UI/UX: * Clean, minimal fintech-style UI (Spice Money / PayNearby type) * Focus on speed, simplicity and usability * UI can be finalized in 1–2 iterations Please include in your proposal: 1. Estimated timeline (days/weeks) 2. Realistic and optimized quote (since backend is already complete and live) 3. Confirmation that app will be native Kotlin (not WebView) 4. Relevant experience in fintech / AEPS / biometric apps (if any) Looking for a long-term technical partner, so please share a practical and honest proposal. Thanks Sabir
