Jorge Lopez focused on enhancing HL7 data testing and validation workflows across CDCgov/trusted-intermediary and CDCgov/prime-reportstream. He developed structured HL7 test data scaffolding, introducing dedicated file containers and example files to support future test automation and maintain repository hygiene. In prime-reportstream, he improved the reliability of HL7 OML pipelines by updating test data to ensure the PD1.4 field was always present, reducing validation errors and strengthening downstream data quality. His work leveraged data engineering and HL7 standards, emphasizing reproducibility and traceability through clear commit practices. The contributions provided foundational improvements for robust, maintainable HL7 data processing.
