I will test etl pipelines, databases, and validate data using sql

I'm a QA engineer with 3 years of experience specialising in ETL testing and data pipeline validation. I help mid-size companies catch data quality issues before they reach production so your dashboards, reports, and downstream systems stay accurate and reliable.

My core skills:

ETL pipeline testing with Apache Airflow workflows

SQL-based data validation across MySQL, PostgreSQL, SQL Server, Snowflake, and BigQuery

Source-to-target reconciliation and row count checks

Schema validation, transformation logic testing, and null/duplicate detection

Writing structured test cases and defect reports

I hold a degree in [Computer Science / IT / your field] and approach every project with clear documentation and timely communication.

If your data moves through a pipeline and you need someone to make sure it arrives correctly, let's talk.
