02 · About Section 02 / 09

A developer who cares about performance & craft.

I’m Sviatoslav — a web developer based in Vlore, Albania, 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 with RTL support, or tightening Core Web Vitals so a marketing team’s investment actually pays off on mobile.

What I do.

Three flavors of engagement, all anchored in the same principle: ship fast sites with editorial freedom baked in.

01 · WordPress

Custom themes & block libraries.

End-to-end WordPress builds from Figma: custom theme, Gutenberg block library with React, ACF-driven content models, multilingual setup with WPML.

  • Theme from scratch
  • Gutenberg blocks (React)
  • ACF · CPT · Taxonomy
  • WPML · RTL support
02 · Frontend

Vue & React interfaces.

SPAs, headless WordPress front-ends, marketing sites, dashboards. Typed, tested, and tuned for Core Web Vitals — not a framework playground.

03 · Perf & CWV

Performance rescue.

Inherit a slow WordPress or headless site? I audit, remove bloat, rebuild the hot paths, and push mobile Lighthouse back into the 90s without an agency contract.
