Sviatoslav Klymenko

Frontend Developer

I build fast, polished web experiences with WordPress, Vue, and modern frontend tools — from custom Gutenberg blocks to complex UI systems.

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.
