    I'm in IT more than 20 years and have lots of practical knowledge.

    Croatia - Last active: 12/17/2013 - Tests: 2

    I'm in IT more than 20 years and have practical knowledge of everthing - hardware, software, networking, security, etc. I am very good in resolving problems others can't and because of my broad knowledge I can provide original and simple solutions for you IT needs and optimize your current solution. Not interesting anymore for most but i was a Certified Netware Engineer but maybe you need a virtualisation of an old Netware server? I can solve your Microsoft OS related problems but prefer Linux related jobs and can help on all issues (from instalation, configuration and any special need ). Had a small hosting company with a partner but we split. While there I maintained the complete Linux hosting service and nowdays maintain a few dozen Linux Internet and Intranet servers in Croatia and other Europe countries. Regarding the web I have developed a bunch of custom web sites, most using Perl+MySQL+JS/jQuery. Also have resolved issues, improved or made updates and upgrades for sites other people have developed in many opensource CMS. In short: if nobody can help you I probably will if it is technically possible.
