John Sietsma

John Sietsma combines a long history as a games and AR developer with a love of education to help people make the most out of Unity. He has worked on games that let people fly planes, play Rugby League, conquer kingdoms, merge the real with the virtual and compose music by waving their arms around! 

Commissioned by Layar, John made one of the first location-based AR games in 2010. While working at Dekko, John pioneered AR game development and design. He now works for Unity as a Technical Evangelist, specializing in AR.
