I need a complete telemedicine solution that lets patients book, meet, and receive prescriptions from clinicians without leaving the app. Also, riders shall be used to pick blood samples and the same done at our office. Medicine dispensed through the same. Referrals to hospital too. The build must cover iOS, Android, and a responsive web portal, all sharing one code-base or, if you prefer native paths, a perfectly aligned user experience. Core features are non-negotiable: real-time video consultations, calendar-driven appointment scheduling, and a prescription module that can generate, store, and forward e-scripts. Two-factor authentication is mandatory for every login flow; propose the provider or library you trust and show how you will keep consultations and health data fully encrypted in transit and at rest. I am open to Flutter, React Native, or separate native stacks, as long as the final product feels fast and intuitive. A lightweight, well-documented REST or GraphQL API, cloud deployment instructions, and automated test coverage are expected. Deliverables • Production-ready iOS, Android, and web apps with video, scheduling, and prescription management fully functional • Admin dashboard, database schema, and source code with clear comments • Two-factor authentication integrated and verified in staging and production • Setup scripts, deployment guide, and a short knowledge-transfer call The project is ready to start as soon as I see a concise roadmap and tech stack proposal.
