Senior🎓
Top SchoolYuqing Jiang is a media-focused software engineer and entrepreneur with 13 years of experience building production-grade streaming and player systems. As Co-Founder of Sumeru Labs and former Media Tech lead at Panda.tv and ByteDance, he has designed client-side live streaming architectures, players and transcoders that scale in real-world deployments. His open-source contributions to xgplayer highlight hands-on expertise in video processing, HLS playback robustness, SEI handling and buffering/fetch loaders—skills that bridge low-level media parsing and frontend delivery. He combines academic training in applied computer science with practical leadership of media engineering teams in Beijing, often tackling the subtle edge cases of live video delivery. Colleagues describe him as quietly pragmatic: he prefers fixing hard bugs and stabilizing systems over flashy demos.
