Full-Stack Mobile Developer — Two-Sided Marketplace App (Expo + Supabase + Stripe Connect)

Looking for an experienced React Native/Expo developer to build a two-sided marketplace mobile app. The product is fully designed — every screen mocked up, backend architecture documented — so this is an execution role, not a discovery project. Stack: Expo/React Native, Supabase (Postgres + RLS), Stripe Connect for payments/payouts, Stripe Identity for verification. Scope for this engagement: build out the core UI screens and connect them to a Supabase backend per provided specs. Additional phases for payments integration and business logic may follow for the right fit. What I need to see in your application: Experience with Expo/React Native shipped to production (link to App Store/Play Store apps a plus) Experience with Supabase, including Row Level Security policies Any experience with Stripe Connect (marketplace payments, not just basic checkout) A short note on how you'd approach a milestone-based, fixed-scope engagement Full spec, mockups, and detailed scope provided to shortlisted candidates after a signed NDA. Budget/type: [set as fixed-price per milestone or hourly — fill in based on your Upwork research]
