   High-Performance Server-Driven UI (SDUI): I developed a dynamic JSON-based rendering engine that successfully optimised frame rates from 30–40 FPS to a stable 60 FPS. This was achieved by implementing the `RepaintBoundary` technique to minimise layer repaints.• Multithreading and Optimisation: I offloaded heavy JSON parsing to Flutter Isolates, preventing UI jank and ensuring smooth user interactions during complex SDUI rendering cycles.• State Management and Architecture: I designed a robust application state using the BLoC pattern and employed Drift (SQLite) as a local reactive database. This enabled real-time data streaming and offline persistence.• Real-time Systems: I integrated WebSockets to facilitate instant wallet balance updates and data synchronisation, thereby enhancing the reliability of financial features.• Networking and Debugging: I developed a centralised networking layer using Dio and integrated Alice for real-time HTTP inspection. This significantly reduced debugging time for the development team.• Cross-Platform Adaptability: I pioneered adaptive UI development to ensure a seamless experience across Android, iOS, and Foldable devices. I utilised responsive design patterns to achieve this.• Security and Support: I implemented secure OAuth 2.0 authentication flows via Google and Telegram. I also integrated the LiveChat SDK for real-time in-app customer support.• Custom Infrastructure: I designed a modular library of reusable widgets and a centralised error-handling system. I utilised custom SnackBar notifications to ensure consistent UX across the platform.
