September 2025 – Delivered developer-focused improvements across two repositories: standardized commit messages in notification-service-api (commitlint replacement), stabilized CI/testing in yjdh (pytest workflow fixes with updated PostgreSQL version, system packages, Python dependencies, and DB connection strings), and updated CODEOWNERS to clarify ownership ( KuVa-developers added; tet removed). These changes improve maintainability, reliability of CI, and clarity of code reviews, delivering business value through faster feedback and stronger governance.
