Built and optimized a device-based fingerprint authentication system by integrating the native Android SDK (Java), improving authentication success rate and reducing auth failure drop-offs in production. Architected real-time data synchronization using WebSockets to keep authentication state and user sessions live across devices without polling. Reduced app load time by ~40% through memoization, lazy loading, and component-level performance audits across large-scale screens. Led development of React Native applications serving thousands of users, owning architecture decisions around security, performance, and native integrations.

Developed scalable mobile applications using React Native, TypeScript, and Expo. Designed navigation architecture using Expo Router (file-based routing) for modular and scalable apps. Implemented real-time communication using WebRTC for proctoring and monitoring systems. Built WebSocket-based systems enabling live data sync across thousands of users. Designed and implemented offline-first voice billing system using Google ML Kit. Built AI-powered pipelines (speech + facial recognition) using ML Kit and TensorFlow Lite. Improved application performance by 40% via optimization and efficient rendering. Owned end-to-end delivery of critical features from design to production rollout. Developed animation-ready UI systems using modern styling libraries (Gluestack / NativeWind).
