Alessandro Ruggeri contributed to the DUNE/sandreco repository by developing and refining remote data processing workflows and enhancing build system reliability. He introduced and later streamlined the reco_cell executable, enabling macro compilation for remote processing and then simplifying the build by removing obsolete components. Using C++ and CMake, Alessandro focused on build hygiene, dependency management, and code refactoring to reduce maintenance overhead and improve onboarding. He also addressed cross-platform compatibility issues and refactored ECAL geometry logic, fixing boundary handling and ensuring correct hit mapping. His work demonstrated depth in build systems, geometry processing, and debugging, resulting in a more maintainable codebase.

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.
