[curtisblaine]

A developer that knows how to treat other people in the team, knows how to be professional, works on what they agreed to during sprint planning, doesn't want to rewrite the project to a new technology and doesn't want to create their own cool project because they know the ultimate goal is to ship to users, doesn't react badly to criticism, is not unreasonably stubborn, has good hygiene, doesn't take code reviews personally and agrees that management has a necessarily different point of view from pure developers.
