Who is this guy?

An adequate answer would be : Kévin Ottens, PhD in Computer Science and KDE contributor. I participated in the creation and acted as board member of the Toulouse LUG: Toulibre. I can also be identified thanks to my GPG key ID 8DEC C9E2, or as ervin from IRC (#kde-devel and other channels on freenode).
