To describe myself using eight words: I am a problem solver with extensive experience. As a Linux server administrator (since 2009), I configured and partly now maintaining servers for,,, and other companies (more than 20 servers including VPSes). Also, I consult clients and colleagues on a wide range of questions related to web development and system administration. Since 1998 till 2009 I used to work as a programmer, participated in a variety of projects including Plesk for Linux. (So, I dealt with PHP3/4/5, Perl, bash, Java (J2EE), Pascal, C, JS; I know design patterns, test-driven development, agile methodologies and so on, and so forth.) During the summer of 2011 I took part in selection of the staff for one company (testing candidates' knowledge of PHP5, OOP, MySQL et cetera; more than 1000 candidates). If you need to develop a UI part (JavaScript/HTML/CSS), I am not the right person. And despite the fact that I know PHP I don't want to use it anymore. Now I am learning Python and Ruby.
