Worked on enhancing ingress control and security for the livekit/protocol and livekit/livekit repositories by introducing a dedicated enable/disable flag for ingress sessions. This feature allowed sessions to be disabled without removing them, preserving stream keys and improving overall security. The implementation involved updating API endpoints and validation logic using Go and Protocol Buffers, ensuring that new connections were rejected when sessions were disabled. Additionally, fixed gating logic in livekit to consistently honor the enabled status across protocol and runtime components, reducing leakage risk. The work demonstrated a focus on backend development, API design, and robust cross-repository consistency.
