I keep a hospital's clinical endpoints running, and I build tools that help protect small businesses.

IT Field Service Technician on the Refresh Team at Vanderbilt University Medical Center (CTG contract). CompTIA A+ and Network+, Security+ in progress. Next step: cyber defense.

What I bring

Reliable in a live hospital. Curious about how it breaks.

I came to IT from trucking, landscaping, and farm work. That background shows up as showing up: finishing the job, talking to the people on the floor, and writing down what I learned.

01

Calm on clinical floors

Go-lives, backfills, and swaps on units with active patients, including a pediatric heart unit and an epilepsy monitoring reading room. I plan around clinical work, not the other way around.

02

I find what the ticket didn't say

Located carts no ticket described, a laptop offline since 2024, and closed a multi-site visit six other technicians hadn't finished, by walking floors and asking the people who use the equipment.

03

Security-minded, and I build things

Phishing trainers, header analyzers, OSINT and DFIR utilities, a PowerShell assessment kit, and an Active Directory home lab. Hands-on practice behind the certifications.

Highlight

Restored a unit's only cardiac data-acquisition path

Remotely installed and configured Philips Holter monitoring software on a replacement acquisition workstation, the only computer in the unit certified to run it. Coordinated around active patient monitoring the whole way.

Result: zero disruption to patient monitoring
Ownership

Closed a multi-site visit six technicians hadn't

Desktop swaps, rename scripting, shared drive mapping, forced updates, and full Pegasus CI asset records, end to end and unsupervised.

Troubleshooting

Tracked down hardware no ticket described

Found two failing WOW cart units by interviewing nurses, pulled the IP over Bomgar, and confirmed location against the Cisco Prime access-point map before swapping.

Imaging & deployment
  • Provisioned and deployed 100+ clinical workstations and WOW carts across multiple floors, from imaging to floor-ready.
  • Ran 32-port KVM/PXE imaging (WinPE + WIM, manual OS and OU selection, no SCCM) and performed a live network switch swap and port remap during a full-day refresh.
  • Wiped, reimaged, and redeployed Windows machines and WOW carts across Nashville, Clarksville, and Tullahoma.
MDM & mobile
  • Provisioned 32+ iOS devices via Intune and Apple Business Manager, including Radiology-specific configurations.
  • Built and pushed floor-specific Intune configuration profiles matched to each unit's clinical workflow.
  • Built cellular charge-nurse iPhone profiles with distinct APN configuration and policy, separate from Wi-Fi-only devices.
Clinical go-lives
  • Supported full go-lives for two Neuro Step Down units: device deployment, network validation, and on-site support through cutover.
  • Worked with a specialized IT group to install and commission epilepsy monitoring equipment in an EMU reading room, then supported its go-live.
  • Executed 4–5 backfill moves with go-lives, adapting to last-minute scope changes; swapped a digital status board on a pediatric heart unit during active use.
Documentation & security
  • Authored SOP-ITS-001, an iOS MDM provisioning runbook; became the team's go-to for MDM workflows after a senior technician left.
  • Used PowerShell to locate IPs on restricted machines and documented how GPO and Intune compliance correctly blocked privilege escalation.
  • Keeps Pegasus CI and the team tracker current after every swap; troubleshoots VMware Horizon VDI sessions; follows HIPAA/PHI device handling throughout.
