At MUFG, I design and implement secure database solutions aligned with federal policies and NIST guidelines. I manage database activity monitoring platforms and develop security policies to support audit and regulatory readiness.

At Duke Energy, I investigated and triaged cybersecurity events across corporate and operational technology environments, resolving over 4,000 events. I also tuned detections and used the MITRE ATT&CK Framework to map threat intelligence for security monitoring.

At Jacobs Engineering, I managed Oracle security through development, user acceptance testing, and launch. Earlier, as Postmaster with the United States Postal Service, I managed mail operations across three offices and conducted audits to maintain SOX and HIPAA compliance.
