During March 2025, Matthias Kleiner focused on enhancing the stability of the AliceO2Group/AliceO2 repository by addressing a targeted issue in the TPC scaler creation process. He implemented a robust error handling mechanism in C++ to detect and manage cases where Intermediate Data Collections (IDCs) were missing. By introducing a guard that logs a warning and halts scaler creation when no IDCs are present, Matthias prevented potential errors and undefined behavior in the data processing pipeline. This work demonstrated careful attention to edge cases and contributed to more reliable software engineering practices, leveraging his expertise in C++ development and error handling.
