I test ETL data pipelines to ensure accurate data migration, transformation, integration, and reconciliation across large datasets.

At Virtusa Consulting Services, I analyze requirements, estimate testing effort, and develop test cases, test plans, and sample data. I write complex SQL queries, validate data, and conduct system integration and functional testing across project iterations.

I also validate Tableau visual analytics reports, analyze fact and dimension tables in Snowflake schemas, and track defects through sprint planning and triage.

Previously at Cognizant Technology Solutions, I developed SQL test scripts and performed metadata, count, duplicate, end-to-end, and regression testing. I collaborated with business analysts and development teams to resolve issues and maintained defect evidence in Rally and ALM.
