I'm Kai (often called KK), Team Lead at Moonshot AI, building our next-generation coding agent. Previously, I worked on AI platform & LLM post-training at Microsoft (in partnership with OpenAI), streaming experience at Disney Streaming, and data visualization at ByteDance.
One thread runs through it all — I love building tools that make people more effective, from visualization research to AI agents, and occasionally just for fun.
