Worked on CDCgov/trusted-intermediary and CDCgov/prime-reportstream, focusing on HL7 data engineering and testing. Built explicit HL7 test data scaffolding to support future Ochsner-related test cases, introducing a dedicated container structure for streamlined test data management without altering business logic. Enhanced the HL7 OML pipeline by updating test data to ensure the PD1.4 field’s presence, reducing validation errors and improving downstream data reliability. Emphasized repository hygiene and traceable commit practices to support reproducibility and auditability. Utilized HL7 standards and data engineering skills to strengthen validation foundations, contributing to more robust test coverage and higher data quality in production workflows.
