About me

Over 8 years of design and development experience in a wide selection of industries and a specific focus on startups.





My main goal with any project is to have a deep technical understanding. I’m very good at breaking down complex problems, finding more effective ways of solving them, optimizing workflow and increasing value. I particularly enjoy organizational problems and I have built a wide selection of internal tools during my career to assist my peers and clients.

I care about designing clean and beautiful UI’s and my passion has even led me to build my own front-end framework to increase development productivity.

I am currently leading product design on the Nedbank design system, working on processes and assisting in building out tools to help the bank internally.

“Stefan is a rare talent. In the short while that he worked with me, he demonstrated a unique ability to break design and code challenges down into their simplest and most eloquent solutions. His innate sense of balancing function and form is something that simply cannot be taught. He is highly integrous in both work and conduct, and will surely blaze trails into his bright professional future. I can highly recommend Stefan as an important addition to any world class team.”

"Stefan is one of the most meticulous and talented designers I have met. He is able to think conceptually, craft and produce content that is both relevant and beautiful. A skilled artist that I would work with again in a heartbeat."
