About

Hi, I’m Chad.

I’m a cybersecurity leader and AI engineer. I’ve worked in enterprise technology for the U.S. Department of War since 1997.

I’m a U.S. Air Force veteran, and I live in Tokyo. My day job is leading a cybersecurity team that keeps defense healthcare systems secure and authorized to operate. I’ve held the CISSP since 2020.
