Enhanced documentation in Markdown and YAML, introducing a Code of Conduct, open-source contribution guidelines, and security reporting processes to streamline onboarding and clarify community policies. Leveraged GitHub Actions to automate releases and enforce consistent workflows. The work emphasized risk reduction, maintainability, and external collaboration, demonstrating depth in CI/CD, documentation, and open-source contribution across multiple repositories.
