End-to-end development & SEO

Launching a website takes a few days. Building one that loads fast, gets indexed reliably and brings in customers is a different task altogether.

I'm a web developer and SEO specialist based in Maribor, Slovenia. I specialize in building modern, fast, and search-optimized websites — from landing pages to complex multi-page portals.

My approach: clean code, thoughtful UX, and SEO baked into the architecture. Every project starts with business analysis, not a template.

I structure content so that it is understood not only by Google but also by AI search: Google AI Overviews, ChatGPT Search and Perplexity.

Frequently asked questions

Do you only build websites, or also handle SEO?

Every project combines development and technical SEO — clean semantic code, structured data, and Core Web Vitals are built in from day one, not added after launch.

Can you build a multilingual website with proper SEO?

Yes — sites in 2 to 4 languages with correct hreflang, language-specific meta tags, and a separate URL structure per locale (e.g. /de/, /ru/, /sl/).

Do you use WordPress or another CMS?

No — sites are built in hand-written HTML, CSS, and JavaScript. No framework overhead, which means faster load times and cleaner SEO.

Do you work with medical and healthcare practices?

Yes — several projects (OsteoMed.si, MTMED.si, Osteo.si) are for therapy and manual medicine practices, where trust, clarity, and local SEO matter most.

How long does a typical project take?

A single-language landing page usually takes 1–2 weeks; a multilingual multi-page site with full SEO setup takes 3–5 weeks, depending on scope.

Do you guarantee a #1 ranking on Google?

No, and nobody can honestly guarantee that. I do not promise first place overnight — I build a solid technical foundation: speed, clean code, correct structure and markup. That is what drives long-term business growth.
