I've mastered software reverse engineering/C/C++/C#/Java/Win API/Assembly programming and helped many customers.
Especially, I've rich experiences of unpacking Themida/WinLicense, VmProtect, and other packing modules.
I've also ever worked for online game maintenance, bug's fixing, and cheat and anticheat developing.
And I have cracked a lot of dongle key(USB, Parallel, and etc) protection mechanisms.
