Worked on the key4hep/k4geo repository to enhance simulation fidelity and maintainability for calorimeter detector studies. Developed and optimized dual-readout calorimeter simulation components by refactoring DRconstructor and FiberDRCaloSDAction, updating steering parameters to improve simulation accuracy and efficiency. Addressed code quality by centralizing SiPM efficiency data management, removing hard-coded dependencies, and eliminating dead code, which prepared the codebase for integration with k4RecCalorimeter. Updated documentation to reflect architectural changes and ensured robust version control through consolidated commits. Demonstrated expertise in C++ and Python, applying code refactoring, detector physics, and Geant4-based simulation techniques to support reliable physics analyses.

Mar 1, 2025March 2025: Key progress on k4geo related to SiPM data management and code quality. Achievements include relocating and centralizing SiPM efficiency data (prepping for k4RecCalorimeter integration) and removing unused variables in FiberDRCaloSDAction.cpp to eliminate dead code. Documentation updated (README) to reflect changes. Impact: reduced technical debt, improved data consistency, and a clearer integration path for the calorimeter backend. Technologies demonstrated: C++, refactoring, code maintenance, and documentation practices.
