• Do you have small projects such as installs and configurations? 
• Are you looking for new network and system design suggestions? 
• Perhaps you can use an extra team member to get a special project organized and completed? 

I have over 20 years of experience using Unix operating systems and over 15 years of experience with a variety of network operating system, general networking, interoperability, installation, configuration, troubleshooting, security, centralization, virtualization, and performance tuning.  I spent several years supporting network operating systems installation and configuration for a large hardware manufacturing company and have been a certified trainer in at least one operating system for 15 years.
