Hire the Best CMS Developers
in Serbia

Full-stack WordPress developer with 10+ years of experience. Most of my clients stay with me for years - I build their sites, then keep them running, secure, and evolving as their business grows. I work with businesses in the US and EU as a long-term technical partner: someone who knows your site inside out, responds fast when something breaks, and doesn't need re-briefing every time you have a new idea. What I handle: ✔ Custom WordPress themes and plugins built from scratch ✔ WooCommerce stores: setup, custom checkout logic, product sync, payment and shipping integrations ✔ Third-party API integrations (CRMs, email marketing, ERPs, custom REST APIs) ✔ Multilingual sites (Polylang/WPML) and complex ACF-based builds ✔ Analytics and tracking: Google Tag Manager, GA4, conversion tracking, consent mode ✔ Performance optimization: Core Web Vitals, caching, image and asset optimization ✔ Security: malware cleanup, hardening, backups, SSL, migrations ✔ PHP troubleshooting, legacy code modernization, MySQL/database work How I work: I'm responsive, direct, and honest about scope. If something can be done simpler or cheaper, I'll tell you. I make targeted changes instead of unnecessary rewrites, document what I do, and never leave you with a site only I can maintain. Open to hourly and fixed contracts, but I do my best work in ongoing relationships where I act as your dedicated WordPress developer. Check my portfolio and reviews below, and feel free to reach out with questions - happy to look at your project and give you a straight answer on what it needs.
