Worked on backend stability improvements for the SBNSoftware/sbndaq-artdaq repository, focusing on message queue readiness and log durability to enhance system reliability and uptime. Addressed a system hang issue by implementing a polling mechanism with a delay, ensuring message queues are created before data is sent. Updated log handling to use append mode, preserving logs across restarts and supporting better post-mortem debugging. These changes improved the startup reliability of the bottom CRT backend and reduced downtime risk. The work leveraged skills in backend development, system programming, and message queues, utilizing C and C++ to deliver targeted, maintainable bug fixes.
