Worked on the MonoGame/MonoGame repository, focusing on enhancing code quality and maintainability within the Matrix.CreateBillboard method. Delivered a targeted refactor using C# to improve variable naming, clarify code intent, and align with established coding standards. The approach emphasized code readability and maintainability, making it easier for future contributors to understand and extend the method without altering its external behavior. This work demonstrated skills in C# programming, game development, and refactoring, and contributed to reducing maintenance risk while supporting onboarding for new developers. No major bugs were addressed during this period, with efforts concentrated on internal code improvements.
