PROFILE
Hao Wu
During a three-month engagement, Hawu contributed to the apache/cloudberry repository by delivering targeted improvements to release processes and disk quota management. Hawu stabilized release artifact naming to align with integration test requirements, enhancing build reproducibility and reducing test failures. In C and Shell, Hawu enhanced the disk quota testing framework with better debugging, performance monitoring, and clearer regression reporting, which improved CI reliability. Further, Hawu optimized disk quota management logic for performance and updated the release pipeline’s versioning strategy using YAML and Makefile scripting. These contributions deepened the repository’s automation, testing rigor, and release process consistency for downstream users.
