He began playing Minecraft in 2010. He got so good at it, that at one point he realized that the Dutch servers were slow, so he spent a month doing upgrade-patches for hMod. In late 2010, he was approached by a company that does it professionally, and he joined their ranks. He was so popular by that point that he attended MineCon in 2011. After MineCon Majong itself approached him about working for them. At first he was hired to modifying the API and maintain the Minecraft server but was later promoted to general game development.
He is also known as Grum or _grum and his skin is a entirely red with yellow markings on his chest.
He married Sharon in May 2012. They are both Dutch but live in Sweden, which is where the Majong headquarters are.
He was approached and hired by Majong after playing and accelerating at Minecraft online, after which he moved to work at the Majong headquarters in Sweden, just like web video star Lydia Winters.
