I’m creating a money-growth platform that onboards users instantly—no ID uploads, selfies, or paperwork. Security will rely on biometrics instead: Touch ID, Face ID and device fingerprinting. The product must launch simultaneously on the web and as iOS/Android apps, sharing one reliable, encrypted back-end. Here’s the flow I’m aiming for: a visitor lands on the site or opens the app, taps a single button, grants biometric permission, and is inside a wallet where funds can be added, tracked and withdrawn just as quickly. The interface must stay lightweight while leaving room for future compliance modules and live payment rails. I’m moving fast and want an MVP in hand as soon as possible. When you reply, focus on your direct experience shipping fintech, banking or crypto tools—tell me what you built, the stack you chose, and how you handled biometric authentication. Deliverables • Responsive web application (React, Vue, or similar) • Native or cross-platform iOS & Android apps with Touch ID / Face ID login • Secure REST or GraphQL back-end, encrypted data storage, JWT/biometric token flow • Deployment scripts plus concise setup documentation I’m on call to answer questions and unblock progress so we can launch ASAP.
