Project Overview
The Challenge
CasesGG needed a mobile platform capable of handling 500K+ concurrent users engaging in real-time activities with instant visual feedback. The app required ultra-smooth animations even during sound streams and live events, with zero lag tolerance for user interactions.
Our Approach
We built a high-performance React Native app leveraging React Native Reanimated and Skia for native-level performance. Complex animations run at 60 FPS on the UI thread while sound streams play simultaneously without dropping frames. Real-time features use WebSocket connections with optimistic UI updates for instant feedback.

Impact & Results
Technical Architecture
High-Performance UI with React Native
- React Native Reanimated 3: All animations run on the UI thread at 60 FPS, even during intensive sound streaming. Gesture-driven interactions with spring physics for natural feel.
- React Native Skia: GPU-accelerated canvas rendering for complex visual effects, particle systems, and custom graphics without performance degradation.
- Sound Stream + Animations: Simultaneous high-quality audio streaming and 60 FPS animations without dropped frames through worklet-based architecture.
- Optimistic Updates: Instant UI feedback with rollback capability for seamless user experience during network operations.
Real-Time Infrastructure
- WebSocket Connections: Persistent connections handling real-time events with automatic reconnection and state sync.
- CloudFlare Workers: Edge computing for ultra-low latency responses and global distribution.
- AWS Infrastructure: Scalable backend services with auto-scaling and load balancing.
- Anti-Fraud Systems: Real-time monitoring and automated threat detection to ensure platform integrity.
Production Reliability
- Sentry Error Tracking: Real-time crash reporting with source maps for instant debugging and resolution.
- Expo OTA Updates: Deploy critical fixes and improvements instantly without app store approval.
- Performance Monitoring: Track FPS, memory usage, and network performance across all user sessions.
Maintenance & Support
- Continuous Monitoring: 24/7 uptime monitoring with automated alerts for any performance degradation or errors.
- Regular Updates: Weekly dependency updates and monthly feature releases to keep the app secure and modern.
- Performance Optimization: Ongoing analysis and optimization of bundle size, memory usage, and rendering performance.
- Dedicated Support: Direct communication channel with development team for rapid issue resolution and feature requests.
