Build iOS & Android Frontend for Existing Platform

I am looking for an experienced mobile developer (React Native or Flutter) to build the iOS and Android applications for an existing, fully-featured web platform.

The platform is a comprehensive app that connects users with local listings, a multi-vendor marketplace, job boards, and event bookings.

You do not need to build any backend infrastructure. The backend is powered by Supabase, and we have 83 documented Edge Functions acting as a complete REST API. Everything from Stripe payments, auth, geocoding, and chat is already built and working on the web. Your job is purely frontend mobile development and API integration.

Key Features to Implement (Mobile UI): Authentication: Email/Password & Profile setup (Supabase Auth). Discovery & Maps: Location-based search, filtering, and interactive map views for local listings. Marketplace: E-commerce product browsing, cart management, and Stripe Checkout integration. Events: Browsing and interacting with job postings and event schedules. User Dashboards: Order history, favorites, real-time chat messaging, and basic account settings. (Note: Complex admin tools and business owner dashboards will remain web-only for now to save scope).

Tech Stack Requirements: Framework: React Native (Expo preferred) or Flutter. (React Native is a plus since our web app is built in React). Backend Integration: Supabase (Database, Storage, Auth) and REST APIs. State Management: Your preferred robust solution.

What I Will Provide:

1. Full API documentation (Route map, endpoints, payload structures).
2. Access to the fully functioning web application for feature reference.
3. Despiration/guidelines for the mobile UI.

Budget & Timeline: Budget: £5,000 - £6,000 (Fixed Price) Timeline: Please propose a realistic timeline in your bid. A milestone-based payment structure is preferred.

To Apply, Please Include:

1. Links to 2-3 apps you have published on the App Store/Google Play.
2. Your preferred framework (React Native vs. Flutter) and why.
3. Confirmation that you are comfortable working with an existing Supabase REST API backend.

Budget: GBP 5000 (Fixed Price)
