Specializing in enterprise computing level support and solutions, since 1995 I've helped organizations streamline IT systems management, and lower overall operational costs. On operating system platforms ranging from Linux, Solaris, Apple Macintosh, Microsoft, Novell & SCO.

Within IT structures I've successfully introduced cultures that embrace kaizen principals; continuous improvement of processes. This has proven to enable rapid assimilation of new technologies, facilitate stronger organizational communications, and has dramatically strengthen an organization's competitive edge.

I am a time-proven quick learner seeking positions exploiting my professional traits as a polymathic systems administrator, with experience on dozens of computing platforms and hundreds of related services. I currently seek to position myself as a team-lead, where the introduction, or furthering, of departmental transparency enables a primary focus in information systems:

• Process automation
• Service virtualization
• Performance optimization

The goals include enabling organizations to successfully:

• Design, merge & migrate systems
• Ensure service stability, and strong security
• Integrate VoIP, T1, and analog voice services
• Develop and implement sound documentation and communication processes
• Design, document and automate processes; inventory, naming schemes, equipment labeling, configuration, auto-build/deployment, and monitoring/on-call goals.
