What I'm looking for

I’m looking for a QA role where I can own end-to-end ETL/Data Warehouse testing—STTM validation, CDC/incremental/full loads, and SQL-based reconciliation—using Agile processes to ensure clean data releases and faster defect resolution.

I’m an ETL Tester with 3+ years of ETL/Data Warehouse testing and 2 years of manual testing experience. I validate end-to-end ETL workflows across staging, data warehouse, and reporting layers, ensuring data integrity at every transformation stage.

I specialize in ETL pipeline validation using source-to-target mapping (STTM), along with incremental and full load testing and Change Data Capture (CDC) scenarios. I use complex SQL queries to validate fact and dimension tables, perform data reconciliation with control totals and aggregation checks, and drive root cause analysis when mismatches appear.

I’ve worked in Agile (Scrum) and Waterfall environments with hands-on testing exposure to Informatica PowerCenter, Oracle DB, and HP ALM/Jira. In projects like CPIL Atom Bank plc and MPDL Carole Nash, I designed ETL test cases, validated loaded target data via SQL, logged and retested defects in HP ALM, and supported regression testing and UAT cycles for stable releases.
