PROFILE
Cterrevo
Contributed to the AliceO2Group/O2Physics repository by developing and refining C++ workflows for high energy and particle physics data analysis. Over three months, delivered features such as enhanced DStar invariant mass analytics, dual-detector PID logic for Xic candidate selection, and a comprehensive refactor of Xic analysis code to improve maintainability and machine learning readiness. Addressed data integrity and stability by fixing track handling bugs and streamlining histogram logic, while introducing QA-driven monitoring for better observability. Leveraged C++ and data processing expertise to reduce technical debt, improve reproducibility, and establish a robust foundation for future physics analysis and ML integration.

Jun 1, 2025June 2025 monthly summary for AliceO2Group/O2Physics focused on code quality improvements and ML-readiness. Delivered a code cleanup and refactor of Xic analysis and HfTaskXic to remove PID track tables, replace magic numbers with constants, reorganize member variables, and update signatures to use aod::TracksWDca. Streamlined ML-oriented data processing by removing unnecessary MC prong acceptance checks and simplifying histogram/data filling logic. These changes establish a cleaner foundation for ML workflows, reduce technical debt, and improve maintainability and reproducibility of physics analyses.
