I've been a Systems Administrator specializing in Linux in various capacities for the past decade and a half, and I'm now in a position providing enterprise services for an organization of over 15000 employees, managing a VMWare/CentOS infrastructure, web traffic using F5 BIG-IP LTMs (mainly managing load balancing and SSL certs, APM custom iApps, iRules, etc.), and more. It's fun and for educational!
