    Hello, my name is Andrii. In my childhood, I spent a lot of time with a soldering iron, making different interesting things. At high school, I got a PC at home and started... Dos, Win, Linux, FreeBSD. At the present time, I have more than 20 years of Win experience and more than 16 years of *nix experience. I like to build systems and solve interesting issues.
