What I'm looking for

I'm looking for a role where I can leverage my 15+ years of experience in ETL, data warehouse testing, and healthcare payer data. My background—especially with organizations like Providence Health Plan and Aetna—has focused on validating complex healthcare data, ensuring accuracy under HIPAA, and driving data transformations across platforms like Snowflake and TriZetto Facets.

At Providence Health Plan, I lead end-to-end ETL and data-warehouse validation for Medicare, Medicaid, pharmacy/PBM, medical claims, ASO operations, and regulatory reporting. I validate SQL-to-Snowflake migrations, source-to-target mappings, transformation logic, and healthcare payer data quality.

Across Providence, Morgan Stanley, Williams-Sonoma, Bank of the West, CSC, and Aetna engagements, I've used complex SQL, Informatica, Teradata, DB2, and automation to reconcile data, resolve defects, and support reliable releases. I also test TriZetto Facets member enrollment, eligibility, coverage, and claims impacts under HIPAA controls.
