Rockstar🎓
Top SchoolRobert Swain is a seasoned software engineer with 20 years of experience specializing in media processing, real-time communication, and systems optimization, currently maintaining the Bevy engine and working on media transcoding at Spotify. He blends low-level multimedia expertise (GStreamer, FFmpeg, physics interpolation) with full-stack and backend systems work, having driven WebRTC, Matrix, and scalable server features in production. Robert regularly contributes to high-profile open-source projects—improving Bevy’s ECS tracing, enhancing Matrix’s WebRTC stack and Dendrite’s backend—demonstrating a talent for performance instrumentation and robust networking. Comfortable toggling between minute implementation details and long-term architectural strategy, he’s also built novel demos like WebVR/web-based VR conferencing and remote-control over mobile networks. Based in Stockholm with a mathematics and physics background from Warwick, he brings an analytical approach to sensing-focused systems and a proven track record of shipping reliable, high-performance multimedia solutions.
