Worked on the AliceO2Group/O2Physics repository, delivering targeted enhancements and reliability fixes for heavy-ion collision data analysis. Developed features such as event-plane based spin alignment for Dstar and normalization of rapidity values in Charm polarization studies, improving data consistency and analysis accuracy. Addressed bugs affecting mass assignment, centrality filtering, and histogram configuration, which enhanced data quality and reduced edge-case failures. Applied C++ programming, data analysis, and scientific computing skills to refactor workflows for maintainability and traceability. The work enabled more robust physics analyses, streamlined analytics pipelines, and supported reproducible research in high energy and particle physics environments.

Aug 1, 2025Performance review for 2025-08: Delivered a robustness fix for centrality filtering in O2Physics, significantly improving stability and data quality in centrality-based selections. Addressed a loop-control bug in taskCharmPolarisation.cxx by replacing an erroneous 'return' with 'continue', ensuring collisions outside the centrality range are skipped rather than exiting the function prematurely. The change is tracked in commit 5589eaba8c3a813861cb5f02541b128850d2dcb2 and PR #12743. This fix reduces edge-case failures, enhances analytics reliability, and shortens debugging cycles. Skills demonstrated include C++ debugging, rigorous code review, and regression-friendly changes with clear traceability to a single repository.
