React Native Developer Needed — Loyalty Rewards App, Phase One (Frontend Only, iOS & Android)

Looking for an experienced React Native developer to build Phase One of a cross-platform mobile app for iOS and Android. The app is a loyalty rewards app where users earn points from purchases and can view their reward token balance. Phase One covers the core app frontend and simple blockchain features. Later phases may add more screens, features, and backend integration. This phase is frontend only — you'll build the app UI and blockchain integration. What you'll do: - Build the mobile app frontend in React Native with TypeScript. - Build the Phase One screens: login, rewards dashboard, transaction history, and profile. - Integrate simple blockchain features: - Display the user's wallet address and reward token balance. - Fetch and show a list of recent token transactions. - Read data from a deployed smart contract via its ABI. - Show a simple "connect wallet" flow. - Implement navigation between screens. - Handle loading states, errors, and form validation on the frontend. - Test the app on real devices or simulators and fix any issues. - Hand over the code with a short README explaining how to run and build it. What I need: - Strong React Native and TypeScript experience. - Basic blockchain experience: reading from smart contracts, fetching wallet balances, and displaying transaction data. - Experience publishing apps to the App Store and Google Play (preferred). - Clean, readable code. - Clear communication and weekly updates. Budget and timeline: - $2,500–$3,000 fixed price, depending on experience. - Complete within 4 weeks. To apply: Include a link to a React Native app you've built (App Store/Google Play link or GitHub repo) and briefly describe one technical challenge you solved in it.
