Hello
I am a professional system administrator in a hosting IT company. So my everyday duties setup servers, upgrade and move sites from testing environment to production, do upgrade for WordPress, Drupal, Joomla, Django, DotNetNuke, Magento and many others.
I am not only know to setup site, but also know how to troubleshoot it: how to check and fix DB integrity, source code permissions and restrictions.
Let's discuss more details via interview.
Thanks.
