Worked on enhancing the CI pipeline for the hiero-ledger/hiero-sdk-cpp repository by enabling TCK unit tests for both Debug and Release builds on Linux. This initiative focused on improving CI/CD reliability and expanding automated test coverage, allowing for earlier detection of defects and reducing integration risks for downstream consumers. Leveraging skills in DevOps, Testing, and YAML, the work established stronger quality gates within the development workflow. By integrating comprehensive unit testing into the CI process, the changes supported faster feedback loops and increased release confidence, although no major bugs were addressed during this period. The contribution deepened the project’s testing infrastructure.
