IndiaWhat I'm looking for
I’m an ETL Tester with 4+ years of experience in ETL testing, data validation, and big data testing across cloud-based data platforms. I focus on ensuring end-to-end data accuracy by validating logistics data pipelines, testing APIs, and verifying transformation logic with SQL.
I’ve worked extensively with Kafka for real-time streaming validation across ingestion, transformation, and storage layers (AWS S3, Athena, MySQL). I also monitor and validate Airflow DAGs and EMR workflows, where I’ve improved Airflow DAG performance by 50% and enhanced data quality by 80% through structured validation and testing practices. I’m comfortable owning defect resolution in JIRA, and I’ve led a team of 4 as the primary QA point of contact for stakeholders.
