Message

At Oracle, I architect and deliver Exadata and OCI solutions for enterprise workloads, including database and Oracle E-Business Suite migrations. I migrated 200+ TB of enterprise databases from on-premises Exadata to ExaCC/ExaCS using XTTS, achieving zero data loss and minimal downtime.

I’ve also led Oracle 12c RAC and non-RAC upgrades to Oracle 19c, and delivered Autonomous Database deployments that reduced operational overhead by 40%. My work includes performance tuning, customer workshops, proofs of concept, and OCI landing zone design.

Earlier at Oracle, I led E-Business Suite migrations and upgrades and tuned database performance using AWR, ASH, and SQL Tuning Advisor, reducing average query response time by 50%. Across my database roles, I’ve worked on RAC, Data Guard, RMAN recovery, Exadata, and cross-platform migrations.
