About me

Portrait of Mate Burazer

Hi — I’m Mate Burazer, a system administrator and network engineer from Croatia. I enjoy tinkering with software and hardware configurations, network setups and everything in between.

From an early age I wanted to be a power user and administrator of whatever I owned, and to know what lies in the depths of every operating system — from everyday PC OSes to unusual mobile ones like MeeGo. That curiosity led me into system and network administration, and I still love it. Away from the console I play video games, read books, watch films and listen to music.
