Worked on the pion/interceptor repository to address a critical memory-management issue in NACK buffer handling, focusing on improving stability and scalability during stream teardown. Implemented robust cleanup logic across the ResponderInterceptor and RTPBuffer components, introducing a Clear method to ensure retained RTP packets are properly released to allocation pools after streams are unbound or closed. Enhanced lifecycle management by expanding cleanup paths and adding comprehensive unit tests to validate memory release scenarios. Collaborated closely with other contributors, demonstrating strong skills in Go, concurrency, and network programming while directly reducing memory growth and improving the reliability of RTP session handling.
