Hello,
I am a professional system administrator in a hosting IT company. So my everyday duties setup servers, backup and move sites from testing environment to production, do upgrade for WordPress, Drupal, Joomla, Django, DotNetNuke, Magento and many others.
I have experience with AWS, Heroku, Rackspace, Azure, GAE and others.
I am not only know to migrate site, but also know how to troubleshoot it: how to check and fix DB integrity, source code permissions and restrictions.
So, any administrator can do this job, but I can do very professionally.
I am very patient, polite and attentive to details.
I can not only fix bugs, but also improve your code or make some advice according the coding.
Thanks
