About me
I have 6 years of experience in a large Windows/Active Directory environment for the USAF but automation is my real passion.
I love learning new skills and expanding my knowledge.
I have over 6 years of professional experience with Windows Workstation and Server Operating Systems, Active Directory, PowerShell. I have worked my way up from a frontline technician to a position where I managed multiple different domains and I feel like I learned many skills that are critical to the industry.
I think what really sets me apart is my drive to learn. I have set up a home lab that I use to learn new operating systems, new software, automation and much more. I’m even self hosting this website in a docker container at home!
What I do
From setup and configuration of servers and workstations to maintaining directory and authentication services for an enterprise and anything in between.

I have been writing scripts to automate daily tasks such as system patching and DISA SCAP/STIGs.
Active Directory & DNS
I have experience supporting multiple active directory deployments, one with over 600 domain controllers and around 900,000 objects.
Server Management
I have years of experience configuring and maintaining Windows servers for multiple different uses.
