Ana Durglishvili contributed to the key4hep/k4geo repository by focusing on code correction, refactoring, and documentation improvements using C++ and Markdown. She addressed two critical bugs over two months, first enhancing documentation clarity for the FCCSWHCalPhiRow_k4geo module by correcting parameter descriptions and resolving ambiguities, which improved maintainability and onboarding for new developers. Later, she fixed an abnormal hadron response in the HCal simulation by applying Birks’ law for Polystyrene scintillators after migration to DDSim, updating both code and README to ensure reproducibility. Her work demonstrated careful attention to simulation accuracy and clear, maintainable documentation practices.
