Fast, lightweight WordPress sites built in Kadence, not the bloated builders that slow you down.
I'm Martynas, a WordPress developer in Lithuania with a QA background, so I test and break my own work before you ever see it.
📈 Every site I've rebuilt went from a PageSpeed score of ~45 to 90+
⚡ I specialize in Kadence for clean, fast, Google-friendly sites
🧪 QA mindset means fewer bugs and fewer "it broke again" messages
What I do:
✅ New builds in Kadence, done right the first time
✅ Fixing broken or half-finished sites (including AI or past-dev messes)
✅ Migrating slow Elementor sites to fast, clean Kadence builds
✅ Booking systems, APIs & integrations
Why me:
AI tools and cheap builders get a site 80% there, then leave you the broken 20% that costs you customers. I'm the human who fixes that last part, properly. No corner-cutting. No disappearing mid-project.
