Worked on establishing foundational code quality improvements for the FZJ-IEK3-VSA/FINE repository by introducing an initial linting standard across the codebase. Focused on enforcing consistent code formatting and style using Python and Jupyter Notebook, the work involved removing unnecessary comments and imports, reorganizing code structure, and updating docstrings to enhance readability. This initiative set a baseline for automated quality checks within continuous integration, supporting earlier defect detection and more consistent code reviews. By standardizing the codebase and integrating linting rules, the developer improved maintainability and readability, laying the groundwork for future development and streamlined collaboration within the project.
