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.
