Kerem is a pretty good designer, but I don't really understand the purpose of this post without context. Honestly, I don't really see what sets his work apart from countless other people who aren't on the front page of dribbble...he just happens to be very savvy at branding himself. I would rather see a designer spotlight on someone who doesn't have a bunch of hype surrounding them, and information about why they deserve to be spotlighted.
Kerem is a great UI designer. Check out his work.
