I was one of four designers who created IBM Graph (along with an excellent backend development organization). Our team designed and built Graph's frontend, and helped optimize the user experience of Graph's API. My biggest responsibility for the project was leading front end development. I also wrote the four "Getting Started" tutorials, and collaborated with the other designers to turn each tutorial into an interactive experience.
Dillon Eversman was our UX designer, Bhavika Shah was our design lead, and Chris Befeld was our visual designer.
