PROFILE

Over 12 years experience in support, engineering, and architecture of systems, network, and applications. My strongest, most current, and most enjoyable knowledge lies within Linux/UNIX systems engineering, administration, and security. I enjoy a challenging work environment and work well within a team environment creating and supporting highly available, secure Linux/UNIX environments. I have a long history of improving productivity and constantly look for ways to improve upon this via various means including but not limited to shell scripting and web based solutions.
