I want to release a cross-platform mobile app (iOS and Android) that lets doctors and patients register, link an ABHA ID, and keep every medical record in one encrypted place. Users will sign in with their mobile number and a one-time-password, so the entire onboarding flow has to feel as quick as a normal messaging app yet meet healthcare-grade security expectations. Core scope • Secure medical record storage: notes, prescriptions, lab files and images must be saved in an encrypted store, then decrypted only on authorised devices. • Doctor & patient profiles: doctors get a verified badge after I approve their credentials from an admin panel; patients can create or claim a profile instantly by entering their ABHA ID, which must be validated through the official API. • ABHA ID integration: after a patient links the ID, their future visits should automatically pull or push records to that identifier for continuity of care. I’m happy for you to pick the stack—Flutter, React Native, or true native—so long as the final apps meet App Store and Google Play guidelines. A lightweight, well-documented backend (Firebase, Supabase, AWS, etc.) that supports end-to-end encryption, role-based access, and OTP delivery will be required. Deliverables at hand-off 1. Source code for both platforms, readable and commented. 2. API / database schema documentation and environment files. 3. Simple web admin panel or scripts for user verification and data audit. 4. Step-by-step deployment notes so I can reproduce the build and launch the apps myself. Once the above items pass a quick test with real ABHA IDs and OTP flows, we’ll wrap up the project. I’m ready to start immediately and will be responsive with any domain knowledge you need.
