React Native Mobile Banking App UI Redesign & Biometric Auth

Category: Mobile Development

Budget: 3000–3000 USDC

We are looking for an experienced React Native developer to revamp the user interface and enhance security features for our existing mobile banking application. The project requires implementing a modern, accessible design system compliant with WCAG 2.1 AA standards, integrating native biometric authentication (FaceID/TouchID and Android Biometrics), and optimizing transaction history rendering for high-volume accounts. Key deliverables include: fully responsive UI components built using Tailwind/NativeWind, end-to-end integration with our secure REST APIs, biometric login flow with JWT token handling, and comprehensive unit tests using Jest. You must have prior experience with fintech apps and secure storage practices (Keychain/Keystore). The expected timeline for completion is 5 to 6 weeks, with milestone-based code reviews and deliverables.
