Created the initial aMule project as fork from xMule to improve his skills in C++/GUI development. Since xMule project had lost "its touch" (and majority of developers), aMule quickly became popular, and more and more developers joined. He strongly supported the idea of community development (as opposed to rather closed development of xMule at the time), which could be seen from the "all-are-ops" mentality he enforced on the IRC channel.
Later, there were some misunderstandings between him and the other developers/community, and he is no longer among us. But he will always be remembered as the starter of the aMule project.
