During April 2025, Keerthi Panga focused on codebase maintenance for the shweatank/Mirafra_LDD_BATCH_2 repository, targeting code cleanliness and long-term maintainability. She refactored the C code by removing the unused Add.c file and its associated student-node addition function, which previously handled linked list operations. This effort reduced dead code, improved repository hygiene, and minimized potential maintenance risks, ultimately streamlining the codebase for future development. Keerthi applied skills in C and C++ refactoring, file management, and git-based change management, demonstrating a methodical approach to code health and enabling safer, more efficient onboarding and feature work for the team.
