I'm the cofounder of GreenStone AI, where I built our system end to end — LLMs producing corporate sustainability disclosures in China. I'd be glad to contribute on the technical side — AI engineering, evals, and how to build generative systems that stay within what can be evidenced — to others in the community doing similar work. In return, I'm looking to connect with people working at the intersection of AI safety and sustainability and to learn how they're approaching it outside China.
