About Me

I am a dedicated Frontend Developer specializing in React, Next.js, JavaScript, and modern CSS frameworks like Tailwind CSS. My focus is on writing clean, modular code and constructing responsive web applications that adapt fluidly across devices. I bridge the gap between design systems and clean implementation, ensuring a premium user experience.

In addition to UI development, I specialize in Technical and Local SEO. I design layouts, service platforms, and booking systems that load fast, achieve Lighthouse scores above 90, and pass Google indexing checks. My goal is to build digital assets that help clients generate organic search visibility and scale their businesses online.
