EDI Senior Business Analyst at Molina Healthcare who migrated 8 states to EDIFECS EM and streamlined claims processing.

At Molina Healthcare, I migrated 8 states to EDIFECS EM and collaborated with state agencies and EDIFECS teams. I also led API requirements for a claims-processing integration that reduced manual data entry by 40% and improved data accuracy across three business units.

Previously, at Mitchell International, I designed EDI client onboarding frameworks and built SQL scripts for encounter validation, claims reconciliation, and HIPAA compliance. I also led implementation of a multi-client repricing solution that generated approximately $7M.
