@debashmitasur

I lead enterprise data platforms across Teradata, BigQuery, replication, and automation.

At HCLTech, I lead a 12-member offshore engineering team supporting enterprise database administration, multi-region replication, and SLA delivery across Google Cloud BigQuery and Teradata.

I own Teradata, BigQuery, IBM CDC, and Fivetran replication platforms end to end. I also work directly with Google Cloud and Teradata engineering teams through upgrades, outages, and database modernization.

I’ve reduced CPU/TCore utilization by up to 91% through query optimization and partition redesign, and I manage production data platforms up to 5 PB. My automation portfolio includes shell scripts, Airflow DAGs, stored procedures, and views that reduce manual work across BigQuery and Teradata.

I’ve built operational improvements with Claude, Gemini, MCP, Jira, and enterprise databases, helping resolve incident tickets up to 40% faster. My background also includes high-availability upgrades, disaster recovery, release governance, and 24/7 production support for financial services and energy data platforms.
