You better listen when Pepa has something to say: his observations and ideas are deep and thoughtful, full of wit, and goes to the heart of the root causes, goes to the soul of your Business. Deep focus and ownership are Pepa´s natural strengths. We still enjoy the timeless benefits of his work on the design of "Marketplace" in Poketka our NFC mobile wallet as a crucial part of the big vision of FintechCloud, a brand new channel and acceleration platform.

I would like to thank Pepa for the brilliant cooperation. I need to emphasize his very honest approach towards the project itself and mainly for the communication. I welcome his ability to perceive project complexity and simultaneously cover all of the details. His ability to keep deadlines or fast communication when it changes, helped us in cooperation with other partners, who also worked on the preparation of the new site.

Working with Pepa was great! I appreciate that in every moment of cooperation he contributed to the team with his ideas and moved the team forward. At the same time, Pepa is always ready to accept and think about the opinions of others. Equally important is Pepa's independence and great communication about potential problems. If someone is looking for a person with a great overview of UX, HCD and CX methodologies, with a clear focus on the users and their needs and at the same time always open, Pepa is the right choice.
