Jan 1, 2026Month: 2026-01. This period delivered packaging and CI/CD improvements for the gem/oq-engine repository. The OpenQuake Packaging Namespace Cleanup simplifies installation by removing __setup__.py from the openquake namespace and updating setup.py to use find_namespace_packages, reducing packaging errors and improving compatibility across environments. CI/CD workflow enhancements in GitHub Actions standardize test execution, eliminate unnecessary directory changes, and clarify pytest invocations, bolstering test reliability and maintainability. While no critical bugs were fixed this month, the work focused on stabilization, reproducibility, and faster onboarding for contributors, translating into smoother deployments and more predictable development cycles. Technologies demonstrated include Python packaging, namespace packaging, and GitHub Actions-based CI/CD, underscoring strong skills in tooling, collaboration, and code quality.
