Profile

I am a Linux Systems Administrator (Intermediate to Senior) that designs and builds infrastructure, does root cause analysis, and builds systems to customer specifications. I have extensive experience using configuration management utilities, such as Puppet and Ansible, to automate the installation and configuration of servers. Having dealt with an inordinate amount of software in the educational environment, I have become adept at troubleshooting and diagnosing all types of hardware and software. My areas of interest are in virtualization, clustered network filesystems, and infrastructure design.
