About

I build the infrastructure around AI agents: the tools, harnesses and networks that let them do real work reliably.

I'm Liu Yang, a master's student in Artificial Intelligence at East China Normal University in Shanghai. My research is on time series; outside of it, I spend most of my time on agents and the systems underneath them.

What I work on

• Agent tooling: browser automation, long-running agent sessions, and the harness layer between models and real work. See codex-telegram-bridge and playwright-cli for code agents.
• Networks & HomeLAB: traffic routing, tunnels and self-hosted infrastructure. See XLAN.NET and my HomeLAB overview.
• Research: time series.
• Following: how agent foundation models are pre-trained and post-trained.

What I write here

Mostly notes from things I've set up, debugged or read closely: networking and self-hosting, Linux and developer tooling, deep learning, and agents. Posts are mainly written in Chinese.

Happy to talk about agent infrastructure, networking, or anything I've written here.
