My name is Mislav and I live in small town near Varaždin, Croatia. I'm currently working full-time as Linux system administrator at maxcom d.o.o and part-time as CEO in my personal company mSys. In mSys, I'm doing similar stuff, so it's mostly based on linux server/system administration (basically everything that is mentioned below under experience). I'm 26 years old and father of two. Apart from family, since childhood, my big passion is also fishing - mostly carp sport fishing with motto: catch and release! Boilies FTW

When it comes to work stuff - the very first time I came in contact with Linux (Ubuntu) was after college in late 2011th and after that in early 2012th with Debian. Since then, I've dropped windows OS completely for work related stuff and switched to Ubuntu. Even now, in 2016, I'm still learning new stuff with some experience from past few years.

"Wait a second, you've dropped windows OS?" As I mentioned, only for work related stuff, I'm still using it for gaming! Yes, I'm a gamer as well. My very first steps were in WoW on private servers, after that Dota on eurobattle.net, then Dota on garena/Dota 2 on steam/Diablo 3/WoW retail/D3 RoS, etc...This days, I'm playing D3 on season and World of Warcraft when I have time (not hardcore), and I've paused with Dota 2 a bit. A side note: I've also tried and successfully configured both WoW and D3 on ubuntu machine through Wine and they were working, however, I do prefer/suggest native Windows for this.
