Summary
Ji Li is an SRE at Netflix with 13 years of deep expertise in large-scale distributed systems, CDN and cloud networking, specializing in network protocol performance for video streaming and object delivery. He has a strong track record driving congestion control optimization, Linux kernel and BPF work, network emulation/testing, and production traffic analysis using big data. Previously a principal engineer and technical leader at Akamai and Tencent Americas, he blends hands-on C/Python/kernel development with coaching and architectural decision-making. His Ph.D. in electrical engineering underpins a research-informed approach to practical systems problems, and early work on FastTCP kernel modules highlights a long history of shipping high-impact TCP performance improvements. Notably, he pairs low-level kernel tuning with large-scale production measurement to close the loop between theory and real-world streaming performance.
