What I'm looking for

I'm looking to build reliable data pipelines and automation that improve data accuracy, compliance, and operational efficiency while growing in data engineering.

At Optum, I automate end-to-end SDOH data transformation and migration processes using SQL and Snowflake. I own critical workflows across EPIC, Unite Us, HRA, AARP_OCSS, BYK, and Eliza.

I converted Eliza outbound processing from Snowpark to Snowflake SQL, improving performance and maintainability while reducing processing time by 30–35%. I also develop encrypted synthetic SDOH test data, remediate invalid records, and monitor inbound member matching for reliable ingestion.

I design Azure Data Factory pipelines and enhance Apache Airflow DAGs to support evolving data-ingestion and orchestration requirements. I also own Python automation frameworks for flat-file extraction and end-to-end data validation.

Earlier, I built BDD automation frameworks and reusable Selenium test scripts for OneCognizant using Java, Cucumber, and TestNG. I bring a practical focus on data accuracy, compliance, automation, and reducing manual effort.
