The redesign of Bitbucket was a huge milestone for Atlassian and for myself. It represented a declaration to the world that they care deeply about design, experience, and usability — and that they trusted me to drive it forward. I was personally responsible for each of the 70+ pages in the application. This meant everything from sketching, wire framing, prototyping, user testing, and ultimately the pixel perfect design.
Much has already been said about the design, especially from the community. Just check out the comments on the bitbucket launch blog.
