During March 2025, Matthew Mattina 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++ that waits for message queue creation before sending, ensuring reliable queue availability. To enhance observability and debugging, he modified the log handling to use append mode, preserving logs across restarts and supporting better traceability. His work centered on backend development and system programming, targeting reliability and uptime for the bottom CRT backend. The depth of his contribution lay in resolving a critical bug that reduced downtime risk and improved system robustness.
