About

My Name is Giannis Kalergis, and I am a System Administrator/Engineer

I consider myself to be a professional all arounder with a passion on *nix variants. Completed my studies in Wales during which I earned my BSc in Computer systems and my MSc in Computer systems Security. Since I strongly believe the only limit is the sky , I am always open in new challenges that would satisfy my eagerness to explore and research in new IT related stuff..
