Over the past year, José de Blas developed advanced features and robust infrastructure for the silvest/HEPfit repository, focusing on Standard Model Effective Field Theory (SMEFT) and collider phenomenology. He engineered new physics models, expanded observable coverage across energy scales, and implemented precision calculations for Higgs and electroweak processes. Using C++ and numerical analysis, José refactored code for maintainability, introduced multi-flavor and polarization-aware frameworks, and improved data integrity with enhanced error handling. His work addressed both feature expansion and bug resolution, resulting in a codebase that supports rigorous global fits, future collider scenarios, and reliable high-energy physics predictions.
