Worked on the EOPF-Sample-Service/eopf-sample-notebooks repository to deliver an update to the contributing guidelines, focusing on standardizing code style and improving the contribution workflow for Jupyter notebooks. The update introduced clear documentation outlining formatting practices using Black and PEP 8 naming conventions, ensuring that all notebook contributions remain consistent and maintainable. By establishing a comprehensive guidelines file in Markdown, the work streamlined onboarding for new contributors and reinforced collaborative development practices. The technical approach emphasized code style guidelines and documentation, with no major bug fixes during the period, resulting in a more organized and readable codebase for ongoing project growth.
