Hi,
I'm Ruzaib.

Oracle Apps DBA & OCI Administrator, 8+ years deep in production Oracle estates — performing installations, migrations, and upgrades across EBS, RAC, Data Guard, and Exadata.

I've been the sole Apps DBA on flagship engagements for Yes Bank, Uganda Revenue Authority, and the University of South Africa, and I currently lead OCI & EBS delivery at Tech Mahindra.
