Worked on enhancing the vertex reconstruction geometry for the IDEA Detector within the key4hep/k4geo repository, focusing on closing geometry definition holes to improve tracking precision and event reconstruction reliability. Applied these geometry updates to both the IDEA and ALLEGRO Vertex detectors, ensuring consistency across detector systems and reducing potential systematic uncertainties. Utilized C++ and Geant4 for detector simulation and geometry modeling, demonstrating attention to cross-repository collaboration and calibration integrity. Maintained a clean, traceable git history with well-documented commits, reflecting a methodical approach to code delivery. The work contributed to more robust physics event reconstruction and detector calibration processes.
