During March 2026, Mjga focused on enhancing the hapifhir/hapi-fhir repository by addressing a critical specification compliance issue related to notification event timestamps. They updated the timestamp type from DateType to InstantType, ensuring alignment with the FHIR standard and improving data integrity across downstream systems. Mjga reinforced this change by implementing targeted unit tests in Java, verifying correct type usage and maintaining robust test coverage. The work also included thorough documentation updates to the changelog, supporting transparency and maintainability. Their contributions demonstrated solid skills in API development, Java, and unit testing, with a focus on reliability and standards compliance.
