Business-oriented UX designer

I'm David, an expert in UX and conversion optimization. I'll make sure your users turn into customers.

With 13 years of experience running my own e-commerce business, I bring more than just great UX — I’m a hands-on partner in your business and strategic decisions.

What I can help you with

I identify what’s blocking your growth and fix it — using data, research, and psychology-based insights.

User Experience Design

Good experiences create happy customers!

📈 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.

Conversion Rate Optimization

A higher conversion rate make your business more profitable!

📝 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.

Results and reliability

That’s what my clients and colleagues value most.

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.

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.

Mário Roženský, CEO - SupportBox.cz

We engaged David on reviewing our employee benefits portal we use globally. He managed to understand the site and the mobile app, along with their shortcomings and main issues from a user perspective as well as an analyst, for all different countries. David was very responsive, punctual and critical in his questioning. The output, which was very well structured, clearly showed that he understood our users’ main issues and was able to come up with actionable recommendations.

The new website made a big impact on UX and lead generation of AAU website. Thanks to great UX all key metrics improved, our lead generation efforts increased by 100% with a significant drop in CPA.

The whole AAU community was very excited about the speed and the design of the website and there was literally no negative feedback from any stakeholders. I would definitely recommend David and his team for anyone looking to seriously improve their website performance.

I worked with David on a company website project. David’s experience, expertise, and input on UX design were extremely valuable and his ideas and suggestions regarding the follow-up process both in graphic design and online marketing were outstanding. He has exceptional drive and gets things done. It’s been a pleasure to work with David, and I would definitely recommend meeting with him.

David joined our e-shop redesign team and it was clear from the very beginning that he understands his job. Thanks to the right procedure, infrastructure design, continuous project validation and user testing, we now have a modern, user-friendly online store that finally converts. However, that’s not all. David is still working on its future growth.I have David to thank for overseeing the redesign of Helveti.cz and switching to a whole new system. It is also due to his work that we now grow faster (approx. by 60 % in turnover, year-over-year, the conversion rate has increased by 32 % and working with the system has become much more effective). We still have a lot of work ahead and I hope David will remain a part of it. I highly recommend him!

Working with David was perfect in all aspects. I especially appreciate his methodical thinking and professionalism. This led not only to strict adherence to deadlines (which is by no means common in this field) but also to his conceptual approach to things, where the client knows exactly what is coming next. It was clear David thinks about the project and that he’s truly invested in achieving optimal results.

Redesigning our online store and switching from a box system was a challenge for us and David was an integral part of the project. From the very beginning, when he asked a lot of questions, to completed wireframes. I also appreciated his help with developer and supplier supervision. After the redesign, we have experienced a year-over-year conversion-rate growth by 33,6 %.

Apart from the absolutely smooth professional cooperation with David, I especially appreciate his business focus. Unlike other consultants, he really focuses on bringing money to you.

David really understands the field of User Experience. It was also due to his suggestions that we increased our online store’s turnover by 300 % in 2020. His proposals are based on a detailed analysis and particularly precise implementation plans.

I have decided to redesign our web, I hired a graphic designer and got a nice graphic design to start with. I invited David to get his opinion. After a couple of sentences, it was clear we needed to go back to the drawing-boards and think everything through again. David led me through many aspects of the project, he carried out a detailed analysis for each web page and prepared wireframes. I am very happy with the results and I already got loads of positive feedback. However, what is more important is that the web delivers on the business goals. Not changing anything else, the number of leads has doubled.
