Over seven months, JDavis engineered and refined advanced physics analysis tools in the IMSA-CMS/CMSAnalysis repository, focusing on Higgs and LeptonJet event processing. Leveraging C++ and the ROOT framework, JDavis implemented modular filters, signal fitting workflows, and robust histogram management to improve data quality and analysis reproducibility. The work included algorithmic enhancements for lepton pairing, tau-specific fitting, and background modeling, as well as systematic refactoring for maintainability and efficiency. By addressing both feature development and critical bug fixes, JDavis delivered a codebase that supports scalable, accurate particle physics analyses and streamlined workflows for downstream research teams.
