At FedEx Trade Networks / FedEx Logistics, I led lifecycle engineering and Linux systems administration, modernizing legacy platforms into resilient hybrid cloud architectures. I implemented Ansible and Bash automation for patching, configuration management, log analysis, and compliance reporting.

At Oath Inc. (Yahoo / Verizon Media), I executed migrations and automation across a 25,000+ Linux and Unix server fleet. I also developed Python tools for provisioning, remediation, and configuration management.

At HSBC Holdings PLC, I led vulnerability management across 45,000+ global Linux/Unix servers and automated remediation workflows to strengthen security baselines. My work supported compliance with financial regulatory requirements.

Across infrastructure and security roles, I’ve administered Linux, Unix, and Windows environments; supported virtualization, storage, and enterprise identity services; and worked in regulated, mission-critical settings. I was recognized for the fastest response time to unauthorized network intrusion among all Air Force bases.
