Hi,

I’m Han Rui, based in Beijing. I work on internet infrastructure systems, and write to capture what I learn along the way.

At ByteDance, I work on video network delivery infrastructure for Douyin and TikTok—spanning edge media services, transport protocols, and building the resource supply system that supports global delivery. I also maintain long-term collaborations with academic partners to bring research thinking into real production problems.

For publications, patents, and talks, see Work.
