At WorldSite, I served as the primary systems and network administrator for a varied network of Linux, Solaris, IRIX, Windows NT, and Novell Netware servers, heterogeneous clients, and Cisco routers and switches. It was here that I refined my UNIX and networking skills by configuring and installing new servers, implementing a security model, maintaining the current infrastructure of over 75 servers, and troubleshooting system problems. This often involved working hands-on with networking equipment, rack-mounting and building servers in our Network Operations Facility, and communicating with customers to resolve issues. My position at WorldSite also required me to support the office LAN, frame-relay circuits, and in-house datacenter. I left WorldSite following their bankruptcy/acquisition, but they went out as the largest hosting and access provider in the Beverly Hills area, with clients such as Paramount Pictures and New Jersey Films.

Ninja Networks, an Internet consulting firm, required a System Administrator for their network of about a dozen Linux Servers and core Cisco network gear. The primary focus of this position was maintaining the reliability of the network and security of the servers. After training the current staff to maintain and troubleshoot the network, I left Ninja Networks to pursue a more challenging/rewarding work environment.
