    As IT expert i have done many projects. I am very strong at setting up whole systems ( OSI layer ). I follow KISS methods. With me is easy to setup system from ground up. I am not picky about what systems to use but i do have experience what to use. For example - to you really need apache or lets go extra pro and do project with lighttpd, nginx or hiawatha web server? Same with operating system. Sometimes is better linux. Sometimes better MS. And there are projects where BSD systems are much better. All depends on need. I can setup these systems easily.
