PROFILE

Derek Groen

Worked on the UCL-CCS/EasyVVUQ repository to modernize and automate the Python packaging and release process. Focused on improving CI/CD workflows by aligning documentation builds and testing infrastructure with current Python packaging standards, including migration to setuptools and expanding test coverage to Python 3.12 and 3.13. Enhanced reliability by managing dependencies with TOML and YAML configuration, and introduced a secure, automated PyPI publishing workflow using GitHub Actions and Twine. These changes reduced manual release steps, improved documentation stability, and enabled safer, faster package distribution, supporting ongoing maintenance and onboarding for contributors while strengthening release automation across environments.
