    I am working as a system administrator since 2009. I am managing servers for wm4d.com and call2ru.com (more than 20 of them including VPSes). Also I deal with a few of the other companies. Keywords are Linux (mostly Debian, CentOS and Ubuntu), MySQL, Apache, Nginx, Varnish, php5-fpm and Nagios. Since 1998 till 2009 I used to work as a programmer, participated in the creation of the user interface of Plesk for Unix; in the development of a statistics and billing system for Academ.org; in a number of projects related to IP telephony for Call2ru.com; in some web projects for LightSoft. (So, I used to work 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.) I have been used to select the staff for one company (testing candidates' knowledge of PHP5, OOP, MySQL et cetera; more than 1000 candidates). The major addition: I know PHP very good but I won't code in it. I can do a code review though. In the moment I am learning Ruby and I am charmed by it.  less
