During March 2025, Matthew Mattson focused on backend stability improvements for the SBNSoftware/sbndaq-artdaq repository. He addressed a system hang issue by implementing a polling mechanism in C and C++ to ensure message queues were available before sending data, which improved reliability and reduced downtime risk. His work also included updating log handling to use append mode, preserving logs across restarts and enhancing traceability for post-mortem debugging. Drawing on skills in backend development, message queues, and system programming, Matthew’s targeted bug fix demonstrated a thoughtful approach to system robustness, though the scope was limited to maintenance rather than new feature development.
