At Sparrow Solutions, I design, develop, and deploy three production React Native apps for iOS and Android. I helped achieve a 95% on-time release rate with shared components and a unified mobile CI/CD pipeline.

I built and integrated Node.js/TypeScript REST APIs for ordering, loyalty, and notifications. I also implemented WebSocket- and Firebase-based live tracking, messaging, and push notifications, cutting crash rates in the Driver app by 30%.

At Masteur, I developed React Native and TypeScript apps for a real-time communication and education platform. I integrated Agora.io and LiveKit for video conferencing, and built instant messaging and interactive game features.

Earlier, during my internship at Influence Consulting, I built the front end and RESTful APIs for a multi-user interactive event platform. WebRTC video chat and live polling increased participant engagement by 25%.
