During May 2025, Midnight Theory refactored the PDK cross-section decorator in the gdsfactory/gdsfactory repository, focusing on centralizing and simplifying cross-section decoration logic. By reusing the core decorator from cross_section.py, they reduced code duplication and removed redundant wrapping from the PDK class, resulting in a cleaner and more maintainable codebase. The refactor preserved existing cross-section storage and management behavior, ensuring no changes to the external API or rendering results. This work demonstrated strong proficiency in Python, the Decorator Pattern, and code refactoring, addressing technical debt and improving the maintainability and testability of cross-section rendering workflows.
