Developer Biography

Jay Stelly holds the position of Senior Software Development Engineer with Valve.

Jay joined Valve from Tetragon where he was lead engineer and 3D engine developer of Virgin's Nanotek Warrior. Before that, he developed titles for Sony Playstation & 3DO. Way before that, he wrote his first computer game (at age 9) and had a game published in a magazine (at age 15).

A native of Cajun Country, Jay finds Northwest buildings too hot (what, no air conditioning?) and the food not hot enough.
