I develop cross-platform mobile apps for Android and iOS using React Native, delivering one codebase that runs natively on both platforms. My experience covers React Native CLI and Expo, Firebase integration (authentication, notifications, real-time data), REST API integration with .NET and other backends, and reusable component libraries that speed up delivery. I handle the full cycle: clean UI implementation, state management, API connectivity, performance tuning, and store-ready builds. Coming from a strong full-stack .NET background, I can build both your mobile app and the backend APIs it depends on, so everything works together seamlessly. Whether you need a new app, a feature added to an existing one, or backend integration, I deliver maintainable code and clear updates throughout. Let's talk about your app idea.
