About Me

operator profile — work & life

I'm a data center and infrastructure technician with 6+ years across mission-critical facility operations, enterprise network administration, and multi-client IT support. Right now I support NVIDIA GB300 NVL72 deployments for an Infrastructure-as-a-Service provider, where I designed and engineered the facility's network and systems before the first rack landed.

Before that role existed, I built the facility's foundation from a greenfield: the network, a high-availability hypervisor cluster, enterprise routing/switching/wireless, camera and door-access systems, and the BMS/EPMS integrations that give operations real-time visibility into power and cooling. I led a 6-technician on-site team through rack commissioning and customer handoff.

The whole stack is fair game — fusion-splicing fiber and swapping QSFP-DD optics, VLAN design, hypervisor HA, Windows Server and Active Directory — and everything gets documented as it's built. Earlier stops include a credit union merger, an MSP serving 30+ clients, a 7-location dental practice, and wireless tower installs.

CompTIA Network+ certified. Security+ in progress.
