PROFILE
David Lawrence
Worked on JeffersonLab/halld_recon over three months, delivering seven features focused on deployment, data analysis, and monitoring workflows. Enhanced portability by embedding dependencies directly in executables using RPATH, reducing reliance on environment variables and simplifying deployment. Improved command line flexibility by supporting ET-prefixed event sources, broadening data ingestion options. Refactored C++ monitoring macros to streamline histogram plotting, event counting, and AI-check logic, resulting in more accurate and responsive monitoring. Introduced debug flags and conditional plotting for cleaner operator experience and reproducible data visualization. Leveraged C++ and Python, applying skills in build systems, code refactoring, data analysis, and visualization throughout development.
