Contributed to the AliceO2Group/O2Physics repository by enhancing data analysis quality and quality assurance for resonance studies. Addressed a critical bug in lambdaAnalysis_pb by correcting DCA and invariant mass axis specifications, which improved the accuracy and reliability of lambda analyses. Developed new quality assurance features for Lambda(1520) and Delta resonance analyses, introducing centrality as a histogram variable and implementing pt-dependent cuts to refine particle identification and event selection. Refactored code to resolve O2-linter errors and standardize filenames, increasing maintainability and CI stability. Demonstrated expertise in C++ programming, data analysis, histogramming, and scientific computing within a collaborative workflow.

May 1, 2026In May 2026, delivered QA enhancements for resonance analyses in AliceO2Group/O2Physics. Added centrality as a QA histogram variable and pt-dependent cuts/configurables for Lambda(1520) and Delta analyses to improve particle identification and event selection. Completed a code refactor to fix O2-linter errors and standardize filenames, boosting CI reliability and maintainability. Expanded QA coverage with standardized histograms to ensure consistent quality metrics across analyses. These changes improve data quality, reproducibility, and developer productivity, demonstrating skills in histogram-based QA, configurables, and lint-friendly refactoring.
