Medicine Delivery App Development

I need a basic Android app for medicine home delivery. The app should support only patient accounts and must include the following features:

- Prescription Upload: Patients can take a photo of their prescription to upload.
- Order Tracking: Patients can track their orders.
- Payment Gateway: Secure payment integration.

Ideal Skills and Experience:
- Android app development
- Experience with secure payment gateways
- UI/UX design for easy navigation
- Familiarity with prescription upload functionalities

Please ensure the app is user-friendly and efficient.
