I want to launch a complete medicine delivery solution built specifically for Android. The overall flow is straightforward: users snap or upload their prescription, place an order, pay within the app, and track the courier in real time, while I manage everything from a separate app admin panel. A classic, easy-to-navigate interface is important to me—think clean typography and familiar layouts rather than ultra-minimal modern trends. Deliverables I need from you: • Full Android app (APK + source) • Prescription upload module • Real-time order tracking screen • Integrated, production-ready payment gateway • Web admin panel for product, order, and user management • Robust backend (APIs, database schema, deployment scripts) • Basic UI style guide reflecting the chosen classic look • Build, install, and API documentation so my in-house team can maintain it Acceptance criteria: each module above must be testable on a staging server; payments should clear in sandbox mode; admin panel must show new orders instantly without manual refresh. If you can cover design, development, and a short hand-over session, please outline your preferred tech stack and estimated timeline when you respond.
