Senior Systems Engineer at Walmart Global Tech. I run white-glove support across macOS and Windows fleets, then build the dashboards, automations, and AI-driven agents that make it effortless—equal parts operator and engineer.
< About Me />
White-glove support by day. Automations & AI by night.
With 10+ years across enterprise IT, executive support, and endpoint operations, I've gone from Help Desk to Senior Systems Engineer at Walmart Global Tech. I've run mixed macOS & Windows fleets through Jamf and Intune, supported heads of state and senior executives, and built ServiceNow dashboards, Python automations, and AI-driven agents that take operational toil off my team's plate.
I believe the best engineers are curious ones — the kind who automate the boring stuff, break things to learn how they work, and ship side projects at 2am because the idea won't let them sleep.
