Giribabu worked on the navgurukul/zuvy-server repository, focusing on improving the reliability and maintainability of the scoring system. Over the course of a month, he centralized all scoring-related constants into a dedicated helper module, streamlining constants management and enhancing code readability across the backend. Using TypeScript, he also addressed a calculation bug by correcting the weightageMcqQuestions variable, ensuring that the combined weightage for coding and MCQ questions accurately sums to 100. His work involved backend development and careful refactoring, reducing the risk of mis-scoring and laying a foundation for consistent, maintainable scoring logic in future updates.
