I'm a Zend Certified PHP Developer with about 15 years of experience. At first PHP started as a hobby. Then I started my own web development company during my free hours besides my full-time job as a system administrator at an ISP, working mostly with CentOS, FreeBSD and Debian servers. The shared hosting servers of the company used the Plesk control panel, so I know my way around Plesk (versions 7.x - 10.x) as well.
Eventually, in 2011 PHP developing became my full-time job. I mostly work with the Symfony2 and CakePHP frameworks and am also active in their communities.
