PROFILE

Sean Dubois

Over a seven-month period, this developer contributed to pion/webrtc and obsproject/obs-studio, focusing on real-time media streaming and communication features. They implemented video bitrate pacing in obs-studio using C++ to optimize streaming stability and reduce bitrate spikes. In pion/webrtc, they enhanced WebRTC DataChannel support for larger messages, improved RTP probing reliability, and delivered a TikTok-style video switching demo with both frontend and backend logic in Go and HTML. Their work included protocol implementation, network programming, and rigorous testing, addressing edge cases such as WASM compatibility and ICE renomination flexibility to improve interoperability, maintainability, and real-time media performance.
