Zoid's first notable work was Threewave CTF, an influential Capture The Flag mod for Quake. Following the massive success of his mod, he was hired by id to design CTF modes for Quake II and Quake III. In 2000, he left id to join Retro Studios and worked as a senior programmer on the first two Metroid Prime games.
After working for a couple of years on an MMO at Carbine Studios, he joined Valve where he worked on DOTA 2.
According to his LinkedIn profile page, he has now left Valve Software to work at Blizzard Entertainment as a Principle Software Engineer.
