About

💻 WHAT I DO I’m a Frontend Developer focused on building fast, accessible, and scalable web applications using modern frontend technologies. I specialize in React.js and Next.js, delivering production-ready solutions with clean architecture, responsive design, and optimized performance. Beyond UI development, I work extensively with API integrations, dynamic routing, and SEO optimization, ensuring applications perform efficiently across devices and search engines. I also use Strapi as a headless CMS to build flexible, content-driven platforms with complete frontend control. What differentiates my work is a strong emphasis on real-world performance metrics such as Lighthouse scores and Core Web Vitals, along with best practices like image optimization, lazy loading, and scalable component design. I build interfaces that are not just visually polished, but reliable and future-ready.
