01 — About Me

Infrastructure that stays up while the city sleeps.

I'm an infrastructure-focused systems professional with hands-on experience in enterprise Linux administration, hybrid cloud operations, and network engineering across government, healthcare, and MSP environments — from managing RHEL EC2 fleets and Ansible patching pipelines to supporting DHS-level mission-critical systems.

Off the clock I run a production-style home lab on Proxmox — self-hosting services with Docker, PostgreSQL, and Nginx — bridging sysadmin depth with emerging cloud engineering skills. I like building automation that quietly removes the toil.
