Open to AI engineering work · Singapore, US & Japan

Hi!
I'm Kwang Yang

AI Engineer, Huawei
Agentic systems & RAG

I build systems that solve real-world problems with AI. These days that means agentic harnesses, browser-control agents, and the evaluation work that keeps them honest.

About

Kwang Yang Chia

I’m an AI Engineer at Huawei working on openJiuwen, an open-sourced agentic harness. My main work is on the subagents, especially the browser-control and the computer-use agents.

Before Huawei I was at Hypersketch, building image retrieval. Before that, two years teaching AI and Data Science at NUS: 150+ students, and the School of Computing’s Honor List of Student Tutors twice.

In my free time I make coffee, and I travel a lot. I also conduct workshops and give talks here and there. Currently open to AI engineering work in Singapore, the US and Japan.
