Stefan Momcilovic

I help e-commerce brands unlock growth, turn attention into action, and transform traffic into meaningful, measurable revenue. For over 5 years, I’ve been passionately focused on conversion optimization and Shopify development, working closely with teams to identify friction points, remove hesitation, and create clear, confident paths to purchase. I don’t just analyze data, I turn insights into impactful improvements that consistently move core KPIs.

I’ve partnered with brands across fashion, home, lifestyle, and multiple DTC verticals, delivering strong, repeatable gains in add-to-cart rates, checkout conversion, revenue per session, and full-funnel performance, on average 5-10% improvement. What motivates my work is understanding the real reasons behind user behavior and turning those insights into sustainable, long-term growth.

I am now looking to bring this expertise to a dedicated team in a full-time capacity.

My approach combines robust quantitative analysis with deep qualitative research, blending GA4, heatmaps, session recordings, and user audits with clear experimentation roadmaps and disciplined A/B testing. This balance allows me to drive reliable results because lasting growth comes from intentional experimentation, thoughtful UX, and confident, data-backed decisions.
