I’m ready to move from concept to launch on a complete student-rental platform that runs smoothly on both Android and iOS. The system revolves around three distinct roles—Student, Owner, and Admin—so solid, role-based access control is essential. Here’s the core vision: • Students browse, filter and book available rooms or apartments, message the Owner in-app, and store their agreement details in one place. • Owners publish new listings, update availability, respond to messages, and confirm payments from their side of the app. • Admins oversee everything—user accounts, listings, bookings, payment disputes, plus high-level reports that show occupancy trends and revenue summaries. I’ll need: 1. Intuitive UI/UX design rooted in common rental-market patterns. 2. Cross-platform mobile development (Flutter, React Native or comparable) tied to a scalable backend with REST or GraphQL APIs. 3. Secure email / social login, push notifications, and an integrated payment gateway. 4. A lightweight web portal or built-in module so Admins can manage data without touching code. 5. Full source code, build instructions, basic test coverage, and deployment support right through to App Store & Google Play approval. If this aligns with your skill set, tell me which tech stack you’d choose, any similar apps you’ve shipped, and a rough timeline to first beta.
