kevallathiya-74/AayuCare ? reverse-engineered prompt

Build me a production ready healthcare app called AayuCare that works for patients, doctors, and admins.

I want a mobile app where patients can sign in, book appointments, view their records and prescriptions, and use a few simple wellness features. Doctors should be able to see their schedule, manage patient workflows, and handle appointments easily. Admins and hospital staff should have a way to manage users, see reports, track activity, and monitor the system.

Please make the backend, authentication, and data handling solid and safe, since this is healthcare data. Use role based access so people only see what they are supposed to, and keep the app ready for real deployment with sensible defaults, health checks, and clean environment based setup. If you need to check current docs or best practices while building, go ahead and look them up.

Make the whole thing feel polished enough for a SaaS product, with the backend and Expo mobile app working together smoothly.
