About

I'm Qing Yan, currently building. This site (rqf.me) is where I write about the products, the engineering, and what I'm learning along the way.

I'm part of Yiling (yiling.top), focused on AI Agent infrastructure with the tagline Agent for Everyone. One of our products is YiShengBan (ear.yiling.top), a children's audiobook app that lets families record their own voices to narrate stories.

Before going indie, my background was in enterprise infrastructure — monoliths to microservices, bare metal to cloud-native, and now to AI. The product philosophy is simple: building an agent should feel like writing a script; using one should feel like sending a message.
