About Me:
Born in 1994, he was just a child when he got his first computer in 2001. Like many children, he spent years playing games until 2007. In 2005, while still a child, he became curious about how games worked and began his research. He first tried to write cheats for games, but that wasn't what he wanted. What he wanted was to analyze how the system worked backwards and have free access to everything, and thus his reverse engineering adventure began. Although he tried to help everyone for free under different identities for years, he realized as he grew older that the industry completely exploited his good intentions, and he created this forum to offer paid services.
