During March 2026, Brett Greenlee enhanced the SBNSoftware repositories, focusing on build stability and data-processing improvements for the 10.20.03 release. In sbnobj, he upgraded the build system and introduced new data structures, leveraging C++ and CMake to streamline dependency management and release workflows. For sbncode, Brett developed modules to extract beam spill data from ICARUS and NuMI, improving the accuracy and efficiency of beam-event processing. He also coordinated dependency and version upgrades across both repositories, ensuring compatibility with updated libraries. Brett’s work emphasized maintainability and reduced risk in downstream analytics, reflecting a methodical and technically sound engineering approach.
