> Daniel Leinerud is a UX unicorn who loves to build stuff: simple, focused apps for Mac, iPhone and iPad, and Back to Lerum, a 3D driving game for the web.

I’m Daniel Leinerud, a UX strategist in Gothenburg, Sweden, and a UX unicorn who loves to build stuff. 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.
