"Stephan is awesome to work with! He shines best when he's faced with hard problems. He demonstrated superior diplomacy and UI/UX mastery in a series of complex projects that we worked on together. He is an evangelist of UX research, and a skilled advocate of user-centric design. I strongly recommend him!" – Chris Pryor
"Stephan is among the best designers I've worked with. While at Cotap together, I was impressed that he doesn't consider his design work done until the product is shipped and working well. He was articulate in product design meetings, eager to embed himself with engineers to get details right, and great at iterating on designs after they shipped. I'd work with him again in a heartbeat." – Christian Niles
