About

My journey started with a Full-Stack course, followed by a year as a junior fullstack developer. Over the past 5+ years, I've specialized in frontend engineering (React, Next.js, TypeScript) and shipped production web and mobile apps end-to-end. I'm driven by measurable impact, code quality, and continual learning.
