I build the layer between people and AI —
making Intent clearer, Ontext recoverable, and Agent behavior controllable.
Agent safety Context Engineer Developer experience
I'm ziqian. I’m pretty good at standing on crowded buses.
Just kidding—though I do pay a lot of attention to stability, what I really love is the timeless, and the craft of designing, building, and getting the details just right.
- Usually I start with frictions. I dig into the cause, understand the mechanism, refine the implementation, and finally turn the solution that's coherent and reliable.
- Most of my projects begin with dogfooding: I build for a problem I experience, use it heavily, and refine it through real feedback.
- Currently looking for internships in AI application engineering, agent infrastructure, or product engineering.
