At Impetus Technologies, I migrate enterprise ETL pipelines from Talend and IBM DataStage to AWS Glue and Apache Airflow. I’ve modernized more than 200 pipelines, improving processing efficiency by 30%.

I translate legacy transformation logic into optimized Python, SQL, Spark SQL, and PySpark workflows. My work has improved query performance by 25%, delivered 99.9% pipeline uptime, and supported BCBSMN and Experian data modernization initiatives.

Previously at CONSAT ORAHI, I built database schemas, ETL workflows, Python automation, and REST API integrations. I focus on data validation, reconciliation, reliable production delivery, and secure data handling.
