Henry Zhang caezium

hi henry here! im just a student trying to learn stuff

I'm currently an assistant researcher at a private quant fund trading Chinese A-shares, where I do quant research and build AI products.

I'm interested in agentic engineering, quantitative research, and racing telemetry — I race karts competitively.

I occasionally participate in academic competitions and kart races.

It's nice meeting you! Feel free to reach out to me.
