I need a full-featured medical app whose main purpose is to handle online consultations between patients and doctors. The flow I have in mind is simple: a patient books a slot, meets the doctor over an integrated video call, and leaves with a digital prescription—while every step is recorded safely in the cloud. Core requirements • Appointment scheduling that lets patients see real-time availability and doctors manage their own calendars. • Patient medical history management so the doctor can review past visits, labs, or images before the call begins. • Prescription management that generates and stores e-prescriptions for the patient immediately after the session. • Secure, low-latency video calls embedded in the app; no third-party links or external downloads. • Cloud storage for consultation recordings and medical files, encrypted in transit and at rest. User roles – Patients: register, verify identity, book, join video sessions, view history, download prescriptions. – Doctors: manage availability, view patient records, conduct the call, write and sign prescriptions. Tech is flexible—as long as the final build works smoothly on iOS, Android, and a modern web browser, and the back-end stack can scale. If you have a favorite combo (e.g., Flutter + Node.js, React Native + Django, or a similar setup) mention it; I’m open as long as we stay fast, secure, and easy to maintain. Deliverables 1. Fully functional app (iOS, Android, web). 2. Back-end with API documentation. 3. Basic deployment scripts for the cloud environment. 4. Short hand-off guide so my in-house team can maintain the platform. Show me previous telehealth or HIPAA/GDPR-compliant work if you have it, outline your preferred tech stack, and estimate a realistic timeline. I’m ready to start right away.
