At Cohesity, I lead database modernization across NetBackup IT Analytics and related product areas, including Oracle-to-PostgreSQL migration, validation, and performance optimization.

I converted, reviewed, and validated more than 400 Oracle database routines for a large-scale PostgreSQL migration program. I also designed and implemented an Oracle 19c installer and upgrade framework for fresh deployments and upgrades from Oracle 11g and 12c.

For Maestro Troubleshooting Agent, I contributed to the architecture of workflows for backup-failure triage, alert correlation, and root cause analysis. Earlier, at Barclays Technology Centre India, I led a team of 11 delivering reporting capabilities for investment banking stakeholders.
