Worked on targeted maintenance within the AliceO2Group/O2DPG repository, focusing on the cleanup of legacy C++ generator configuration files related to heavy flavor decay simulations and triggers. Addressed a longstanding source of potential misconfigurations and build or run issues by removing obsolete GeneratorHF.C-based configurations, thereby improving the stability of the simulation workflow. Applied skills in code cleanup, particle physics, and simulation configuration to align the repository with current generator practices. This effort reduced the maintenance burden and helped ensure future development and CI pipelines remain robust, reflecting a methodical approach to technical debt and workflow modernization in C++.
