Worked on the AliceO2Group/AliceO2 repository to address a targeted issue in the TPC scaler creation process, focusing on robust error handling in C++. Implemented a guard to detect and manage cases where Intermediate Data Collections (IDCs) were missing, ensuring the scaler creation would not proceed under invalid conditions. This approach included logging a warning to alert users to the absence of IDCs, thereby preventing potential errors and undefined behavior in the data processing pipeline. The work demonstrated careful attention to software engineering principles, emphasizing stability and maintainability through precise C++ development and thoughtful handling of edge cases.
