PROFILE
Ana A.
Worked on the uhh-cms/cmsdb repository to enhance data handling and processing accuracy for high-energy physics datasets, focusing on Higgs, Drell-Yan, and Electroweak analyses. Used Python and scientific computing techniques to adjust file counts, merging factors, and implement mechanisms for skipping broken files, thereby improving data integrity and processing throughput. Refactored data pipelines and updated cross-section values to ensure accurate physics calculations and reduce maintenance overhead. Addressed a critical bug by restoring missing cross-section data, which safeguarded against biased analyses. Demonstrated strengths in Python scripting, data analysis, and dataset management, delivering robust solutions for complex scientific data workflows.
