About

Senior Web Developer with 9+ years of experience specializing in high-performance React and Next.js applications.

I am a Senior Engineer with a deep mastery of JavaScript and TypeScript. While I specialize in the React ecosystem, my extensive background allows me to adapt to any tech stack or framework as project requirements evolve. I bridge the gap between complex design files and clean, scalable code.
