During July 2025, contributed to the github/awesome-copilot repository by developing and documenting an Object Calisthenics Guidelines enforcement mechanism for backend code. This work centered on creating a comprehensive Markdown instruction file that standardizes business domain code, promoting maintainability and robustness. The approach emphasized backend development and code quality assurance, establishing a reproducible quality gate that streamlines onboarding for new engineers and sets a scalable foundation for future refactoring. No bugs were addressed during this period, as efforts focused on documentation-driven development and disciplined commit management, demonstrating a strong grasp of software design principles and backend code governance.
