During a two-month engagement, Daniel Groen built and enhanced CI/CD workflows for the UCL-CCS/EasyVVUQ repository, focusing on Python packaging and release automation. He modernized the documentation and testing infrastructure by aligning CI with setuptools, expanding Python version support, and improving dependency management using TOML and YAML. Daniel also implemented a secure, automated PyPI publishing workflow with GitHub Actions, integrating Twine for streamlined package distribution and enforcing environment-specific release configurations. His work reduced manual release steps, improved documentation reliability, and broadened test coverage, demonstrating depth in CI/CD tooling, Python packaging, and workflow automation for sustainable project maintenance and onboarding.

January 2025 — UCL-CCS/EasyVVUQ: Delivered a secure, automated PyPI publishing workflow and strengthened release automation across environments. The work focused on hardening CI for Python package releases and reducing manual steps, enabling faster, more reliable distributions to PyPI. Key improvements included a consolidated GitHub Actions workflow with environment-specific release configuration, mandatory ID token write permissions, and integration of the Twine upload step to publish dist/* automatically. Indentation and workflow associations were corrected to ensure the Build and Publish job triggers are consistently applied across runs.
