# Daniel Leinerud > Daniel Leinerud is a UX unicorn who loves to build stuff: simple, focused apps for Mac, iPhone and iPad, and games for the web: Back to Lerum, a 3D driving game, and Nära nog, a map game. I’m Daniel Leinerud, a UX unicorn in Gothenburg, Sweden. By day I help teams figure out what to make and why. On the side I make it myself: simple tools for Mac, iPhone and iPad that each do a single job, and now and then something for the web.
