A proven record of improving IT operations, securing endpoints and leading modern workplace initiatives.

Standard Fiber LLC

M365 Modern Workplace Administrator

2017–2025

At Standard Fiber I modernized the company’s endpoint management strategy using Windows Autopilot and Intune to provision and secure devices from first boot. I built an internal knowledge hub and produced training videos to empower users and reduce repeat tickets, automated common onboarding and service tasks with PowerShell and Python, and led E5 security deployments including MFA, Defender baselines and Purview DLP. I also managed domains and DNS, improved email deliverability with SPF/DKIM/DMARC, introduced Teams Rooms and RingCentral for collaboration and advised leadership on IT policy and Exchange Online operations.

S3C Inc

Senior System Administrator

2005–2017

Serving as the sole IT administrator at this 10‑person ASIC hardware startup, I provided 24/7 support across Windows, macOS and Linux environments used for automotive sensor design. I consolidated infrastructure by virtualizing Active Directory, DHCP, DNS and print servers on a single ESXi host; installed firewalls and switches and ran structured cabling to deliver reliable wired and wireless access. I designed and maintained the company website in WordPress, documented ISO 9000 compliant procedures and recovery guides, and ensured smooth operations for both office and lab.

Early Career

IT & Communications

1995–2005

During my early career I provided daily IT support for Sandis, a multi‑office civil engineering firm—maintaining AutoCAD workstations and licensing servers, leading organization‑wide OS upgrades from Windows 98 to XP and migrating email from on‑premise Exchange to hosted services. As Manager of Information Systems at Texas Instruments I oversaw systems administration for 150+ users, ensured reliable backups through daily tape rotations and delivered desktop support in Windows NT environments. I also served as a communications specialist at AT&T Wireless, delivering front‑line technical support and outstanding customer service for mobile subscribers.
