I need a complete end-to-end marketplace where private-aviation customers can search, compare and book charter flights while operators list their aircraft and manage incoming requests. The core flows are straightforward: real-time aircraft booking, in-app customer support (chat, ticketing and FAQs) and a revenue-sharing marketplace model that lets each operator set availability and pricing. The product must be accessible on both a responsive web app and mobile apps for iOS and Android; with mobile app being most important. From the user side, the interface should remain identical across devices; from the tech side, a single code-base with shared business logic is preferred to keep maintenance lean. Three distinct roles have to be accounted for: • Customers – create accounts, browse aircraft, submit trip details, receive instant or negotiated quotes, pay securely, and open support chats. • Service Providers – list aircraft, manage schedules, respond to quote requests, see analytics on fleet utilisation and revenue. • Admin – full dashboard for user management, dispute resolution, commission settings, content moderation and system analytics. Key expectations • Fast, intuitive search with filters (range, aircraft type, seats, amenities). • Real-time or near-real-time pricing fed either by operator input or integrated quoting API. • Secure payment gateway with escrow logic to protect both sides until flight completion. • Push notifications, email alerts and SMS for critical events (quote accepted, flight reminder, support reply). • Scalable architecture (AWS, GCP or similar) and modular code so additional services—such as flight tracking—can be bolted on later. • Clean UI built with a modern framework (React / React Native, Flutter or similar) and a well-documented REST or GraphQL backend. Acceptance criteria 1. Web app deployed on a production domain with SSL. 2. iOS & Android apps approved for TestFlight / Play Console testing. 3. All three user roles operate without role leakage; permissions matrix documented. 4. End-to-end booking tested with sandbox payments and support ticket resolution. 5. Source code, environment variables template, and database schema delivered in a private repo. If any part of the scope needs clarification, let me know early so we can lock requirements before development starts.
