Site Reliability & AI Infrastructure Engineer

I design, secure, and operate high-performance systems across public, private, and hybrid cloud environments. My work sits at the intersection of platform engineering, AI infrastructure, observability, security, and systems software.

Good performance is not subjective. Writing about myself is, which is why I had someone else write this README.
