I'm leading cloud migration work at Teradata, designing data synchronization and disaster-recovery architecture on AWS and Azure for American Airlines, BNSF, and Admiral.

I build scalable ETL and data migration solutions, automate Data Mover jobs with UNIX shell and Python, and develop backup and recovery strategies that protect data integrity and availability.

Previously, I led ETL implementation for Tech Mahindra's Singtel Optus engagement, creating Hive tables and partitions, validating Hadoop data, supporting CI/CD pipelines, and designing scalable data warehouse models.

Across TekSystem, Capgemini, and Tata Consultancy Services, I've delivered Informatica-based data integration, performance tuning, production support, and warehouse solutions across Teradata, Oracle, SQL Server, and Hadoop environments.
