I've delivered Oracle DBA support for DoD contractors, Deloitte, Northrop Grumman, General Dynamics, and Booz Allen Hamilton, improving database and healthcare workload performance by 60–80%. I manage Oracle 12c/19c, RAC, Exadata Cloud@Customer, OCI, Data Guard, RMAN, upgrades, migrations, patching, and 24/7 production operations.
I partner with application, ETL, BI, development, and QA teams to validate releases, resolve critical SQL, connectivity, reporting, and performance issues, and maintain reliable healthcare and federal systems. I've strengthened compliance and resilience through STIG hardening, vulnerability remediation, FedRAMP/FISMA/NIST-aligned operations, failover testing, recovery validation, automation, and operational run-books.
