I need a l mobile marketplace that lets people buy and sell individual skill sessions. At launch there will be just two skills (I’ll confirm which ones once the build starts) but the codebase should be flexible so I can add more later without major re-work. Core user flow • Buyer browses a skill, picks a time, and submits a booking. • Seller can accept, deny, or suggest another slot; the request can bounce back and forth until the seller finally taps Approve. • When approved, the buyer is charged and both parties get real-time notifications. Tech and features • Single shared codebase for iOS and Android—Flutter or React Native with Firebase, Supabase, or a similarly lean backend would be ideal, but I’m open to your proven stack. • Phone number verification is the only login method. • Push notifications, in-app chat, and a lightweight admin panel for managing users, listings, and payouts. • Clean UI that’s App Store / Play Store ready. Timeline I’d like a testable build, bug-fix cycle, and store-submission support wrapped up within a month. Deliverables & acceptance 1. Source code, build scripts, and deployment docs. 2. iOS TestFlight + Android internal testing releases passing basic QA. 3. Admin panel with create/read/approve/update/delete/refund for bookings. 4. End-to-end booking loop demonstrated on both platforms. 5. Assistance through initial App Store and Play Store submission. If this scope fits your expertise, let’s get moving—my goal is to keep the project straightforward, fast, and ready for users in the next four weeks.
