I am a DevOps Engineer / Site Reliability Engineer focusing on configuration, automation, and infrastructure-as-code. An expert in highly available, fault tolerant web infrastructure, I have architected and deployed web infrastructure supporting the business operations of Fortune 50 companies.

When not working, I am often contributing to open source projects. I run several open source projects, which can be found in my Projects

If you are in the market for best-in-class IT and technical consulting, I am available through Campbell Tech Solutions, my employer. If you are looking for one-off consulting other other specialty services check out my Consulting page.

I am not currently looking for employment, nor am I looking to leave my current employer. I am not currently looking to network with Recruiters in the metro-Detroit area.
