I’m a 17+ years experienced ETL Testing and Data Automation professional and trainer, currently working at Amazon. I help QA engineers and data testers build practical skills for real-world projects and interviews. My expertise includes ETL & Data Warehouse Testing, SQL, Python, Pandas, PySpark, Databricks, Snowflake, Data Quality, Source-to-Target Validation, Reconciliation, and ETL Automation Testing. I conduct practical, project-based training focused on real-time ETL testing scenarios, automation frameworks, data validation, and interview preparation. My goal is to help testers move from manual ETL validation to automation and become confident in handling real-world data testing projects.
