Objectives
- Build a high-performance mobile app using React Native.
- Integrate a secure payment gateway with Stripe.
- Implement user authentication and personalized profiles.
- Develop a real-time inventory management system.
Technical Challenges & Solutions
Ensuring consistent performance across different devices.
"Initial builds showed performance dips on older Android devices, especially during list scrolling and animations."
Solution: Implemented FlatList for optimized list rendering and used `react-native-reanimated` for more performant, native-driven animations.
Results:
- Achieved smooth 60 FPS scrolling on all target devices.
- Reduced app startup time by 30%.
Complex state management for shopping cart and user sessions.
"Managing the shopping cart state, which needed to persist across sessions and sync with the backend, was becoming complex with component-level state."
Solution: Integrated Redux Toolkit for centralized and predictable state management.
Results:
- Simplified state logic and made debugging easier.
- Ensured cart state was reliably synced and persisted.
