About
I'm not a freelancer with a portfolio.
I'm Darjan Hren, a Shopify conversion rate optimization consultant and designer based in Slovenia, working remotely with Shopify brands worldwide. I co-founded Skuology to solve one specific problem: Shopify stores that get traffic but don't convert. We refined the Baseline Framework across 90+ Shopify projects, where conversion rate lifts of 20 to 50%+ are typical, with outliers of 100%+ conversion rate improvements. Then we built Upsellr to automate the order-value logic we kept designing manually for clients. When you work with me, you're not hiring a designer for a project. You get a system built on 20 years of web and UX design and 10+ years of CRO and A/B testing: the research process, the design methodology, the upsell architecture, and the tracking setup that compounds it all.

About
A growth partner, not a hired hand.
I co-founded Skuology to solve a specific problem: Shopify stores that look fine but don't convert. We built the Baseline Framework across 90+ stores and built Upsellr to automate AOV growth at scale. When you work with me, you get the system behind all of it, not just a designer for hire.
