Worked on stabilizing and unifying codebases across FirelyTeam/firely-net-sdk and hapifhir/hapi-fhir, focusing on integration readiness and maintainability. Led two manual synchronization batches in the Firely-net-sdk repository, aligning feature and develop branches through 30 targeted commits. Upgraded Microsoft.Extensions.Caching.Memory to version 10.0.9, reducing runtime risk and improving dependency hygiene. In hapifhir/hapi-fhir, developed uplift preparation tests for Jackson-Tools-3, validating Java class compatibility ahead of deprecation changes. Emphasized cross-repository coordination, commit hygiene, and project configuration using C#, Java, and XML. The work prioritized smoother releases, robust dependency management, and enhanced software testing without introducing new bug fixes this period.
