Worked on the livekit/sip repository to enhance system reliability and audio processing for SIP-based real-time communication. Focused on backend development using Go, the work included hardening monitor startup by guarding CPU statistics access and deferring updates until initialization completed, which reduced crash risk during rapid deployments. Delivered cross-platform integration testing, notably adding macOS support through Docker and Mage, improving test coverage and platform parity. Refactored the audio pipeline by implementing a configurable jitter buffer and moving audio processing into the input pipeline, which improved audio quality and reliability. Addressed jitter buffer data handling to ensure robust RTP packet processing and testing.
