Alessandro Ruggeri contributed to the DUNE/sandreco repository by developing and refining build system infrastructure and geometry processing features using C++ and CMake. Over three months, he introduced a remote processing utility, streamlined build dependencies, and refactored ECAL geometry code to improve maintainability and cross-platform compatibility. His work included removing obsolete executables, simplifying package discovery, and addressing boundary logic bugs to ensure correct hit mapping in physics simulations. By focusing on code readability, build hygiene, and portability, Alessandro enabled faster onboarding, more reliable CI, and a cleaner foundation for future extensions, demonstrating depth in build systems, debugging, and geometry calculation.
January 2025 – DUNE/sandreco delivered stability improvements, portability, and a foundational ECAL geometry refactor to enable easier future extensions. The work focused on fixing boundary logic, ensuring correct hit mapping, and aligning code with modern C++ standards across platforms.

Month 2024-11: Delivered a Build System Cleanup and Simplification in DUNE/sandreco. The effort combined two commits to streamline the build: removal of the obsolete reco_cell executable, simplification of ROOT package discovery, and removal of commented debug statements to improve readability and maintainability. This build-system refactor is non-user-visible but reduces maintenance burden and lowers risk of future build issues. The work lays groundwork for faster onboarding and more reliable CI.

Month 2024-10: Key enhancements to DUNE/sandreco focused on remote processing workflow and build hygiene. Introduced a new reco_cell executable to compile a macro for remote processing and streamlined dependencies by removing unused RDataFrame inclusions from CMakeLists.txt and StructLinkDef.h. No major bugs fixed this month. Impact: enables remote data processing at scale with faster builds and clearer maintenance paths, reducing build noise and potential misconfigurations. Skills demonstrated: CMake/build-system hygiene, C++ macro tooling, remote processing design, code cleanup.
