Worked on preparing and refining the FamilyMemberHistory feature for the NIH-NCPI/ncpi-fhir-ig-2 repository, focusing on code cleanup, formatting corrections, and comprehensive documentation updates. Leveraged Java and FHIR standards to ensure the new feature aligned with project requirements and maintained consistency across the codebase. Improved repository hygiene by updating ignore files, which streamlined development workflows and reduced unnecessary noise during code reviews. Enhanced documentation coverage provided clearer context for reviewers and future maintainers, supporting smoother integration and ongoing maintenance. The work emphasized careful attention to detail and process, resulting in a feature that was ready for efficient merging and delivery.
