What I'm looking for

I’m looking to lead OCI/Exadata and Autonomous Database operations, deliver zero-downtime migrations and high-availability designs, and use automation to improve reliability for mission-critical enterprise platforms.

I’m a results-driven Oracle Database Administrator and Oracle Cloud Infrastructure (OCI) / Exadata specialist with 16+ years of hands-on experience. I’ve built deep expertise across Exadata Database Machine Administration (DMA), Oracle Database Appliance (ODA) administration, RAC, Data Guard, RMAN, and GoldenGate replication—backed by 16+ Oracle certifications, including OCI Architect Professional, Exadata X8M, RAC & Grid, Data Guard, and GoldenGate.

Since 2021, I’ve been leading OCI/Exadata operations at Rakuten India, single-handedly supporting one of Japan’s largest payment platforms (RPay). I drive On-Prem Exadata to OCI ExaCC Autonomous Database migrations using RMAN Duplicate, GoldenGate Zero Downtime Replication, and ZDM; I also manage ExaCC patching with custom DB home images and DBaaScli automation.

Previously at Oracle Corporation Global Customer Support, I supported enterprise Exadata deployments worldwide as a Situation Manager, troubleshooting complex Exadata/RAC/ODA issues and coordinating resolutions with Engineering. Earlier at Fujitsu Consulting and Rotary International, I administered Oracle RAC and Data Guard, implemented Oracle 12c multitenant, led cloning and DR drills, and delivered mentoring, training, and RCA to strengthen operational reliability.
