In July 2025, Egbert Groenen enhanced the NNPDF/nnpdf repository by refining jet observable data configurations for ATLAS and CMS analyses at 7 and 8 TeV. He focused on improving data integrity by restructuring YAML-based configuration files, breaking broad entries into precise, binned datasets to support more accurate physics analysis. Egbert also addressed a metadata issue by correcting data binning and FK_tables listings, ensuring reliable theory-data comparisons and accurate plotting. His work demonstrated careful data configuration management and version control, applying skills in data configuration and physics analysis to deliver targeted improvements within a focused, high-impact development cycle.
