I already have the full front-end UI of a ride-hailing app built in FlutterFlow and a starter template you can extend. Now I need the core logic finished so the product feels as seamless as Uber. Here’s the scope in plain language: • Backend integration – I’m fine with either Firebase or Supabase, so choose whichever lets you move fastest and keep the architecture clean. • Driver-to-rider matching – real-time assignment logic plus status updates visible to both sides. • Maps API work – show each party’s live location on the map and keep the feed responsive as they move. • Stripe payments – basic card capture and charge flow are partly wired; you’ll polish and prove a successful transaction from request to receipt. • Admin tweaks – any checklist items I send (edge-case screens, error states, etc.) get ticked off before delivery. You’ll receive: the existing FlutterFlow project, current Stripe keys, and my detailed checklist of remaining tasks. Final deliverables are an updated FlutterFlow workspace, any custom Dart actions, and clear deployment instructions so I can one-click publish. Fixed budget is US $600 in 3 milestones—set aside enough hours only if that works for you. Timing is flexible, but steady communication via GitHub or your preferred tracker is essential. Once you reply, I’ll share the checklist and we can get rolling.
