About Me
Developer who cares about performance & craft
With 5+ years of professional experience, I specialize in WordPress, custom Gutenberg blocks, and modern frontend frameworks like Vue.js and React. My focus is clean, performant code — whether it’s migrating legacy ACF layouts to React-based blocks, building multilingual sites, or optimizing Core Web Vitals.
