Worked on the AliceO2Group/AliceO2 repository to enhance calibration reliability for the TRD Gain and VdExB path, focusing on improving numerical stability in calibration workflows. Addressed a calibration edge-case by replacing TMath::Abs with std::fabs for floating-point comparisons, which led to more accurate and robust calibration results. This targeted update reduced edge-case behavior and contributed to higher data quality and more reliable physics analyses. Utilized modern C++ practices, calibration techniques, and numerical analysis to ensure maintainability and precision within a high-stakes instrumentation pipeline, demonstrating careful attention to code quality and the specific needs of scientific data processing.
