Front-End Developer • React • TypeScript • Next.js

As a Front-End Developer with 4+ years of commercial experience, I build fast, scalable, and user-focused web applications that help businesses grow. My expertise with React, JavaScript, TypeScript, and Next.js allows me to deliver clean architecture, high performance, and smooth user experiences that directly improve product metrics.
