Hi, I'm Jason Cat.Welcome to my personal site.

I'm 21 and based in Nanjing, Jiangsu. I graduated from Nanjing University of Posts and Telecommunications. I currently focus on Agent Harness, Agent Runtime, execution security, and cross-platform engineering, working to eliminate silent failures at the boundaries of code, paths, streams, state, and credentials in AI agent runtimes.

I have contributed extensively to several popular open-source projects (see Open Source), helping design and ship multiple features. I'm currently a preselected intern in the Apache Casbin 2026 Tomorrow's Stars program and an organization member of projects including OpenAgent and LoopX.

Technical articles I have written reached No. 1 site-wide on V2EX, Zhihu (both during the Apache Tomorrow's Stars program), and Nowcoder. I have also worked inside a high-profile startup backed by a top-tier VC and an early-stage startup, independently building enterprise AI applications from zero to one and attracting interest from multiple institutions.

Through continuous learning and practice, I hope to become an excellent, widely recognized developer and do work that truly matters.
