Marko Petrovic

I am a Shopify developer with over 7 years of hands-on Shopify experience and a decade in web development. I specialize in pixel‑perfect custom page development, theme customization, and integrating third‑party services to extend store functionality.

I have designed and customized Shopify themes for 50+ clients across retail, fashion, and SaaS, and I have implemented custom Liquid templates, dynamic sections, and bespoke checkout flows that improved conversions and user experience.

My work focuses on performance and reliability — I boosted client site load times by 40% through code optimization and follow best practices for SEO, responsive design, and version control. I collaborate closely with designers, marketers, and backend engineers within Agile/Scrum teams.

I hold a B.S. in Computer Science from UCLA and certifications including Shopify Partner Academy (Theme Development), Google Analytics, and HubSpot Inbound Marketing. I enjoy migrating stores to Shopify, building high‑performance storefronts, and creating subscription and recurring billing solutions.
