About

I’m a seasoned Full-Stack Engineer who thrives at the intersection of UI/UX design and scalable software engineering. I build clean, performant web applications that feel as good as they look, delivering pixel-perfect interfaces backed by robust code and thoughtful architecture.

My core strengths are in React, Vue, Astro and cloud-based platforms (GCP). I enjoy creating custom CMS solutions, optimizing high-traffic sites, and turning complex requirements into reliable, maintainable systems.
