About

I am a self-taught frontend developer with 3 years of experience building with React, Next.js, TypeScript, and Vue.js. I transform self-directed learning into solid technical expertise and enjoy crafting high-performance web applications.

My portfolio features 89+ projects focusing on performance optimization, advanced web animations (GSAP, Framer Motion), and scalable architectures. I earned an Exceptional Distinction during a remote internship with DevelopersHub and ranked top 3 in the Enzo Ustariz 2024 contest. I’m eager to contribute as a frontend/web developer and thrive in collaborative, Agile environments.
