I am a Skilled React Developer with over 8 years of experience building scalable and high-performance web applications. I specialize in React, Next.js, TypeScript, and Node.js, with a strong focus on creating modular and maintainable front-end architectures. Throughout my career, I have led Ul overhauls, migrated legacy systems to modern frameworks, and optimized serverless architectures to improve performance and reduce costs. I have extensive experience integrating complex systems, including REST APIs, blockchain features, and Al-powered solutions, into user-friendly interfaces. Mentoring junior developers and collaborating with cross-functional teams has been a key part of my approach, ensuring high-quality, consistent outcomes. I am passionate about delivering solutions that balance technical excellence with exceptional user experience, and I continuously stay up-to-date with emerging front-end technologies. My goal is to drive innovation while building robust, maintainable, and impactful web applications. PROFESSIONAL EXPERIENCE
