Worked on the Kamailio SIP server, focusing on stability and memory safety within core subsystems. Addressed critical bugs in dialog profile linking to prevent memory corruption and crashes under concurrent load, applying careful concurrency control and memory management in C. Improved SIP server reliability by fixing a NULL dereference in DTMF event handling and eliminating transaction leaks, directly enhancing uptime for high-traffic deployments. Refined atomic operation logic to ensure proper resource cleanup for refcount-guarded objects, reducing memory growth in long-running services. All changes were delivered to the kamailio/kamailio repository, emphasizing robust system programming and network programming practices.
