March 2026 — AliceO2Group/O2Physics: Delivered CCDB Integration Test Performance Optimization, removing repeated CCDB calls to speed up tests and reduce processing overhead. No major bugs fixed this month. Overall impact: faster CI feedback, more reliable test runs, and groundwork for broader CCDB efficiency. Technologies/skills demonstrated: performance optimization, test engineering, cross-module collaboration, and familiarity with common test utilities.

July 2025 performance snapshot focusing on data-analysis features and numerical correctness across O2Physics and AliceO2. Delivered a new Track Count Histogram with an optional statistics-range restriction, enabling granular data analysis and more precise PWGCF correlations. Fixed a bug in StepTHn weight variance calculation by correcting the initialization of mSumw2 and the sum of squared weights, and by clarifying explicit Sumw2 usage. These changes enhance data quality, reliability of physics analyses, and maintainability across repos.

June 2025 - AliceO2Group/O2Physics: Reliability improvements in axis handling and enhanced granularity in tracking efficiency histograms. Delivered concrete changes that increase the robustness of data visualizations and the precision of efficiency measurements, supporting faster analysis and more reliable physics conclusions for June 2025.
