About Rajesh Babu

I’m a certified Oracle Cloud, Application, and Database Administrator with hands-on delivery across implementations, R12 upgrades, and cloud migrations on OCI, Azure, and AWS. I’ve led projects end-to-end—from design to cutover—while aligning security, performance, and cost.

Recent roles include Sr/Lead Oracle Apps DBA and Principal Consultant, delivering complex upgrades, SSO integrations, and platform moves to Exadata/OCI and Azure.
