Hello there,
I am currently working as a Senior System Administrator at one of the biggest web hosting companies from Romania ([login to view URL]). The company is listed as top 5 web hosting companies in my country. I have over 10 years experience working on linux servers and I take care of over 250 servers (both physical server and virtual servers). We are using CentOS linux mostly but also Debian, Slackware, Redhat, Suse for our clients virtual servers. I am familiar with all the virtualization technologies (vmware, xen, proxmox, kvm, openvz etc). We are using cPanel/WHM, webmin + virtualmin and centos webpanel (CWP) as a web hosting control panel. Most of our clients have website built in wordpress/joomla/prestashop or other php/mysql custom made scripts so I am familiar with debugging of these types of platforms, fixing security issues and anything else related. I can also improve your server security and optimize it for speed and low consumption of cpu/ram resources.
If you have any questions I am at your disposal.
Kind regards,
Bogdan
