About

Frontend Developer with 3+ years of experience building scalable web applications using the React ecosystem. I focus on delivering end-to-end frontend solutions - from component architecture and state management to API integration and performance optimization. In my current role, I develop production-ready applications using React.js, Next.js, and TypeScript, building reusable UI components, integrating REST APIs, and optimizing application performance while collaborating closely with designers and backend teams. Core expertise: • React.js & Next.js development • TypeScript and scalable frontend architecture • Redux and state management • REST API integration (Axios) • Performance optimization and UI refactoring • Component-driven development and clean code practices My GitHub profile represents my development journey and earlier projects. After losing access to my previous GitHub account, I am actively rebuilding my portfolio and continuously adding new work as I strengthen my engineering skills. I’m passionate about building maintainable, high-quality frontend applications and open to opportunities where I can contribute to impactful products using modern web technologies.
