Worked on the AliceO2Group/AliceO2 repository, delivering two targeted features over two months focused on core C++ development and algorithm design. Refactored dynamic column data retrieval by replacing a generic template function with a type-safe getColumnValue accessor, reducing post-rebase risk and improving code readability and maintainability. Additionally, optimized the groupTable processing path by removing a redundant empty-table check, simplifying the code and reducing conditional branching while preserving correct behavior. Both changes leveraged advanced C++ techniques, including template metaprogramming and data structures, resulting in cleaner, more maintainable code and laying the groundwork for future performance improvements in dynamic data access.
