Message

At CVS Health, I translate Medicare and Medicaid requirements for enrollment, eligibility, and claims processing into functional specifications, user stories, and testable business scenarios. I also validate payer data with SQL and support UAT and regulatory readiness.

Previously, I worked on hospital revenue cycle requirements at Edward Hospital and payer system enhancements at Optum / UnitedHealth Group. At Kaiser Permanente, I supported member account, billing, enrollment, and eligibility workflows, including data validation and system enhancement testing.
