AI Engineer · LLM Systems

I build and write about AI systems.

Hi there, I’m Ken. I’m currently an AI engineer building enterprise AI products in Singapore. I grew up in Shenzhen, China, and spent a few years in Shanghai for my bachelor’s before moving to Singapore for my master’s degree.

Right now, my work focus on context retrieval, agent harness, evaluation, and making AI behave reliably in production. I set up this site as a space to share my notes, thoughts, and what I'm learning along the way.

When I’m away from the keyboard, I’m probably out playing badminton.
