Business-oriented UX designer
My name is David and I am here to boost the business performance of your project, using my expertise in UX and Conversion Rate Optimization (CRO).
I have been running a successful e-commerce business myself for 10 years, so I know the challenges one faces. That is why I think as an entrepreneur first and as a designer second.


What I can help you with
I make informed decisions based on data, research and my knowledge of psychology. I always do a precise diagnosis first, followed by a prescription.
User Experience Design
Good experiences create happy customers!
📝 I have a systematic, time-proven process for growing online businesses. I can perform a one-off CRO audit, however, we get much better results with long-term strategic work and A/B testing.
Conversion Rate Optimization
A higher conversion rate make your business more profitable!
📈 I will enhance the overall experience on each and every touchpoint of your product user journey. Better UX based on data and research will ultimately lead to more conversions.
Results and reliability
Everything will turn out fine. My clients and colleagues can confirm that.


David is one of the greatest UX professionals with whom I have had the pleasure to work. He's proactive, he brings his own ideas, he understands the business idea of the project and - which is rarely the case - he meets deadlines.
Miroslav Uďan, CEO - Shoptet.cz

David is a very capable UX designer with great enthusiasm for the results of his work. I really like his thinking and his approach to work, which you can seldom see.
Jan Kvasnička, UX designer

I am very content with the results. But more importantly - the website fulfills our business goals. Without changing anything else, the number of leads has doubled.
