I've been in the IT field for over 15+ years. Most of that time has been within the government sector, so I specialize in the Microsoft product suite. I like to think of myself as a jack of all trades, but have been lately focusing on SQL database. I am also familiar with virtualization.
I am familiar with all networking fundamentals and understand how network traffic makes it from point A to point B. I have worked IT for companies as little as a few employees to maintaining a network that serves 100,000+ users.
