I want a cross-platform bus booking application that cleanly separates three user roles—passengers, bus operators, and administrators—while keeping the overall experience fast, intuitive, and secure. Passenger side • Search and Book Tickets in real time, with seat selection and instant fare calculation. • View Booking History for quick re-booking or refund requests. • Receive Notifications (payment confirmations, schedule changes, boarding reminders). Operator portal • Manage Bus Schedules from a web or in-app dashboard: add routes, edit departure times, set seat maps. • Monitor Bookings live so staff can see remaining capacity and passenger lists. • Generate Reports on sales, occupancy, and route performance that can be exported to CSV or PDF. Administrator console Admins should have full user management plus the ability to override schedules, reset passwords, and audit transactions. Core expectations – One unified back-end (REST or GraphQL) powering iOS, Android, and a lightweight web dashboard. – Clean UI built with React Native, Flutter, or a comparable framework; I’m open to suggestions if performance and maintainability are addressed. – Secure authentication, role-based access control, and well-documented APIs. – Source code in a private repo and a short hand-off session once everything is tested. If any part of the flow needs clarification, let me know early so we can lock the scope before development starts.
