What I'm looking for

I'm looking for a dedicated Snowflake Administration or hybrid data platform role where I can apply hands-on production experience in cloud database operations, governance, observability, performance tuning, and high availability.

At HCL Technologies, I manage production operations for 3,000+ DB2 databases, building and recovering HADR and Queue Replication channels while delivering upgrades, SAP patching, DDL changes, and datacenter migrations.

I also administer Snowflake production environments, from RBAC, zero-copy cloning, and Time Travel recovery to multi-cluster warehouse tuning. I use Datadog, Grafana, ServiceNow, and automation tooling to improve reliability, visibility, query performance, and cloud cost control.
