Who I Am — and Why You Can Trust Me

Alexandr Demchenko – freelance CRO consultant for ecommerce and SaaS brands

Freelance CRO consultant with 8+ years of experience helping websites convert better through UX research, A/B testing, and actionable audits.

I’m a certified Conversion Rate Optimization (CRO) consultant with over 8 years of hands-on experience helping businesses improve performance through better UX, research, and experimentation.

I started as a marketing manager in a local company — and eventually became Head of CRO at one of Europe’s leading performance marketing agencies, focused exclusively on high-volume eCommerce brands.

Today, I work independently as a freelance CRO specialist, partnering with fast-growing digital teams across the US, UK, and EU to turn website traffic into consistent revenue growth.

I’ve completed 40+ CRO projects, blending deep behavioral research, actionable audits, and continuous testing to deliver measurable results.

Let’s talk and explore how I can help your website convert better.

More About My Work as a Freelance CRO Consultant

As a freelance CRO consultant, I help eCommerce, SaaS, and B2B brands unlock more value from their existing website traffic. My approach combines UX research, heatmap and behavior analysis, and A/B testing to identify conversion bottlenecks and improve performance.

Whether you need a one-time CRO audit, research or an ongoing part-time CRO specialist, I bring 8+ years of experience and a proven process to every project. I work across platforms like Shopify, WordPress, and Wix, using tools like Hotjar, GA4, and VWO to gather insights and validate ideas through experimentation.

I specialize in turning complex user journeys into clear, actionable paths that drive conversions and sales. My clients typically seek to improve checkout flows, reduce bounce rates, and increase their AOV or ROAS — and that’s where my work delivers measurable results.

If you’re looking for a conversion optimization expert who understands both the technical side and the human side of UX, I’m here to help you increase revenue, not just metrics.
