Built and imaged the servers using ILO and Symantec Ghost since all the servers were located in remote datacenters across the world. Built a BigBrother monitoring server to monitor and alert when servers encounter problems: Disk space, Application/system errors, etc. This allowed us to stabilize our environment by identifying and resolving the small problems before they could compound into major problems.

Installed, administered and maintained live audio and video encoding systems.
