About Kakelversch


Thoughtful digital design for complex products

I am Samir Foundou and Kakelversch is my design practice. As a freelance UX/UI Designer and Digital Product Strategist, I transform intricate business challenges into intuitive, user-friendly interfaces. Based in Nijmegen, I work on-site or on a hybrid basis for various national and international top brands. With over 18 years of dedicated experience in the digital domain, I bring the calm, seniority, and high-level perspective needed to successfully design complex portals and e-commerce platforms. I combine strategic thinking with a sharp, creative vision.

Why Kakelversch?

My focus lies in product strategy, information architecture, and logical user flows. Only when that foundation is razor-sharp does the user experience truly take shape. Whether it concerns complex portals, e-commerce platforms, configuration tools, or the smart integration of AI solutions that deliver measurable value, I ensure that the design perfectly aligns with user needs and business objectives.


With a background at leading organizations and digital agencies, I bring the seniority required to fully understand large-scale projects.


Strategic thinking with a hands-on mentality

Since founding Kakelversch in 2011, I have served as a direct sparring partner for my clients. I gladly take ownership of projects, work data-driven through AI research and user testing, and advise stakeholders to achieve validated product outcomes. You get the expertise of an experienced specialist, combined with the short lines of communication and flexibility of an easily accessible freelancer.
