Contributed to the AliceO2Group/O2Physics repository by developing and refining core features for physics data analysis and simulation. Delivered phi-dependent track tuning parametrizations and collision-aware ITS track filtering, introducing new data structures and configuration-driven options to enhance precision and scalability in track parameter corrections. Addressed a critical sign error in DCA mean correction, improving the reliability of data-analysis pipelines. Implemented collision event filtering enhancements for DPG track processing, enabling more refined event selection. The work combined C++ development, CMake-based configuration management, and advanced data processing, resulting in improved data quality, storage efficiency, and readiness for large-scale physics analyses.
