Pruthvi Suryadevara worked on aligning the High Granularity Calorimeter (HGCAL) geometry definitions with v18 and v19 versions in the SegmentLinking/cmssw repository. Focusing on detector simulation and geometry, Pruthvi introduced new cell types and adjusted existing ones to ensure accurate cell areas and valid configurations, directly improving the fidelity of simulation models. The work included refactoring the HGCalCellOffset logic in C++ to reduce complexity and enhance maintainability, addressing redundant cell type checks for clearer code structure. Over the course of one month, Pruthvi’s contributions improved code readability and reduced configuration risk, demonstrating depth in C++ development and code refactoring.
