An individual who, through an excess of inappropriate concerns, creative conflicts, or lack of expertise or discipline, systematically sidetracks and delays artistic or technical projects, effectively sending such projects to 'Development Hell.'

Also dev-hellion.
"Let's not put Tim on this project. It's on a strict timetable, and he's kind of a development hellion."
