Cross-Platform Marketplace App
How we built a React Native marketplace app that achieved 4.8 star rating, 100K+ downloads, and 85% user retention with seamless iOS/Android experience.
The Challenge
Our client needed to rapidly enter the competitive marketplace app space with limited budget and tight timeline constraints. They required native-quality apps for both iOS and Android while maintaining a single codebase to reduce development costs and time-to-market.
Key challenges included:
- Achieving native performance on both platforms with single codebase
- Implementing complex marketplace features like real-time chat and payments
- Ensuring smooth user experience with offline capabilities
- Building trust and safety features for peer-to-peer transactions
- Scaling to handle rapid user growth from day one
Our Solution
We developed a feature-rich marketplace app using React Native with platform-specific optimizations. The app includes advanced search, real-time messaging, secure payments, and comprehensive user verification systems.
Technical Architecture
- Frontend: React Native with TypeScript and Redux Toolkit
- Navigation: React Navigation with deep linking support
- Backend: Firebase with custom Cloud Functions
- Payments: Stripe integration with escrow system
- Real-time: WebSocket connections for chat and notifications
- Storage: Async Storage with Redux Persist for offline access
Key Features Implemented
- Advanced product search with filters and geolocation
- Real-time messaging with image and file sharing
- Secure payment processing with buyer protection
- User verification and reputation system
- Push notifications for offers, messages, and updates
- Offline browsing with data synchronization
