I have used Linux in my personal life since 1998. At home I run two 4U servers running 14 virtual machines and as many as 60 virtual machines during experiments. I love computers; to me they're more than just a paycheck.

I have professionally worked in I.T. with a primary focus on Linux systems since 2004. I advanced from being a help-desk technician into Linux systems administrator, where for four years, I deployed and maintained over 800 physical servers located all over the world. After my experiences with systems administration, I moved into a split instructor/consultant role, which I have been acting in for the last ten years.

As a consultant, I've gained outstanding real-world hands-on experience deploying new environments and supporting existing infrastructure. I've completed successful consultant work for Moody's, DICK'S Sporting Goods, Capital One, H-E-B, and many others.

As an instructor, I teach classes of students how to correctly use Linux and Linux-related technologies, including Red Hat® Enterprise Linux, Kubernetes, Ansible, Hadoop, Docker, Chef, Puppet, and many, many other technologies which are listed below.

A notable consulting experience

As a consultant, I worked with a large specialty grocery store. I was brought out to help the company upgrade a large existing Red Hat Satellite 5 deployment to Red Hat Satellite 6. This was no small task, over a period of two weeks, I deployed two Satellite 6 servers, multiple capsule servers and set it all up in a high-availability active-passive setup. I worked with the on-site admins to plan data migration from the existing Satellite 5 servers, and eventually moved all data, licenses, and registered clients to the new Satellite 6 install.

Further, I developed several Puppet modules which were used to ensure a consistent deployment across the company's nearly 15,000 servers. These modules were responsible for ensuring ssh keys were deployed, enabling registrations to Red Hat IdM, synchronizing sudo rules, and configuring remote logging.

Technical Overview

I've had the opportunity to work with many different technologies, and I have a proven track record of being able to rapidly adopt new and upcoming technologies.
