Worked on refactoring the PDK cross-section decorator in the gdsfactory/gdsfactory repository, focusing on centralizing and simplifying cross-section decoration logic. Leveraged the Decorator Pattern and Python to reuse the core decorator from cross_section.py, which reduced code duplication and eliminated redundant wrapping in the PDK class. The approach maintained existing cross-section storage and management behavior, ensuring no changes to the external API or rendering results. This targeted refactor improved the maintainability, readability, and testability of cross-section rendering across the codebase. The work demonstrated a methodical approach to reducing technical debt while preserving business value and system stability.
