Sobre mí
I craft lightning-fast web applications with 13+ years of programming experience. Specializing in performance optimization, I've cut load times by 65%, improved Lighthouse scores from 72 to 94, and built systems handling 10,000+ items without lag.
My expertise spans React, Next.js, TypeScript and Web3. I've optimized NFT marketplaces, e-commerce platforms, and complex applications, always focused on measurable results. I don't just write code—I solve real business problems through clean, optimized solutions.
Need a developer who obsesses over performance and user experience? Contact me!
