K. Schulze established foundational code quality improvements for the FZJ-IEK3-VSA/FINE repository by introducing an initial linting standard across the project. Using Python and Jupyter Notebook, Schulze standardized code formatting, reorganized the code structure, and updated docstrings to enhance readability and maintainability. The work included removing unnecessary comments and imports, which reduced codebase noise and clarified intent for future contributors. By integrating these linting rules, Schulze enabled automated quality checks within the continuous integration pipeline, supporting earlier defect detection and more consistent code reviews. This effort laid the groundwork for ongoing code quality and maintainability within the FINE project.
