Experienced FlutterFlow & Xano Developer Needed for Intercity Transit App

Project Overview: We are launching "Fast Track," an intercity shuttle service operating a fixed daily schedule with 3 passenger vans across 6 regional cities. We need a dedicated no-code freelancer to build a native iOS and Android application ecosystem. Required Tech Stack: - Frontend: FlutterFlow (Must support compilation for official Apple & Google App Stores) - Backend/Database: Xano or Supabase (Must handle relational data and prevent ticket race conditions) - Payments: Stripe (Including native mobile SDK for Tap-to-Pay walk-up fares) - Notifications/Map: Firebase & Google Maps API Core Features to Build: 1. Customer App: Route search (Origin/Destination/Date), multi-hop ticket booking, Stripe payment, and an in-app digital ticket displaying a dynamic QR code. Includes a live map tracking the incoming van. 2. Driver App: Simple digital passenger manifest checklist with a native camera QR code scanner. Features a [Tap to Pay] button leveraging mobile NFC to process walk-up credit card sales. 3. Strict Inventory Constraints: Vans are capped at 25 passengers. Each van features a built-in wheelchair lift but can strictly accommodate exactly ONE (1) wheelchair booking per trip leg. The database must automatically lock out wheelchair availability across all overlapping legs of a route once that single slot is purchased. 4. Cancellation Rules: Automated conditional logic to handle cash refunds (less than 24 hours notice) or issue an in-app 90-day travel voucher code (2 to 24 hours notice). To Apply: "Start your application with the phrase 'FAST TRACK SYSTEM' so I know you actually read our requirements." Please provide links to functional mobile apps you have built utilizing FlutterFlow and an external backend like Xano. Explain your experience working with Stripe payment integrations and complex database inventory logic.
