I need a seasoned React Native developer who can turn my mobile auction concept into a polished iOS + Android application. The product is an auction-style e-commerce app where Buyers, Sellers, and an Administrator interact around live, timer-based auctions with real-time updates. Tech stack you must be comfortable with • React Native + React Navigation for a seamless cross-platform UI • Axios for RESTful calls to my backend • Redux for local state and TanStack Query for server state & caching • Socket.io Client to broadcast live bids and timer events instantly • Stripe React Native SDK for secure payments and escrow release • Firebase Cloud Messaging for push notifications • OAuth-based social sign-in (Google, Apple, Facebook) • Cloudinary for fast, reliable image / media handling • Native component styling that fits both iOS and Android conventions Core features to implement • Live bidding rooms that stream bids in real time • Accurate, synchronized auction timers • Buyer/Seller ratings and reviews for trust and transparency • Role-based flows for Buyers, Sellers, and Administrators • Real-time messenger Scope of work 1. Architect the project, set up navigation, Redux store, and TanStack Query configuration. 2. Build Buyer and Seller flows: item listing, catalogue, live auction screen, and checkout with Stripe. 3. Integrate Socket.io so bids and timers update instantly without polling. 4. Push notifications via FCM to alert users when they’re out-bid or an auction ends. 5. Social authentication through OAuth for frictionless onboarding. 6. Cloudinary integration for media upload, transformation, and delivery. 7. Native-styled components with attention to light/dark modes and accessibility. 8. Simple in-app (or web-view) admin dashboard to monitor auctions and manage users. 9. Unit and integration tests, a basic CI workflow, and store-ready builds for App Store & Google Play. 10. Concise developer documentation covering setup, environments, and deployment. Deliverables are the complete source code, signed builds, and documentation that lets another engineer step in without guesswork. If you’ve shipped production React Native apps with live data and in-app payments, I’d love to see them. Please outline your estimated timeline and any questions you have so we can move quickly.
