About

Who I Am

I'm a Senior React Developer with over a decade of hands-on experience building scalable, performant web and mobile applications. My journey began with vanilla JavaScript and HTML/CSS, and I've evolved through the entire modern frontend ecosystem.

I specialize in React.js and React Native, with deep expertise in state management using Redux and Redux-Saga. On the backend, I work with Node.js/Express and Python/FastAPI to build robust APIs and services.

I'm passionate about real-time communication — having built production systems with WebSocket and Webhooks — and I thrive in environments where code quality, performance, and user experience are paramount.
