Hi! I'm an ML Research Engineer currently working on LLMs & AI Agents at a startup in Shanghai, China. I have 8 year experience on NLP & Software Engineering. I'm also an SCPD student in Artificial Intelligence at Stanford University currently researching on LMs & generative AI, and an alumni of University of California, Berkeley in Computer Science.

I co-founded and worked as CTO in startups Whimly LLC. and Beijing Youli Technology Co., Ltd focus on Travel and Social Networking web / mobile applications. I also worked as Principal Software Engineer and the AI Lead in Veeva Systems China on CRM system.

I researched and implemented an easy to hack Backpack Language Models repository in Stanford University mentored by John Hewitt, and achieved best custom project on CS224N (2023). The refined work was accepted by BlackboxNLP 2023.

I co-founded academic NGO Jungus and maintained the personality/psychological tests services with annually 5M+ testers and collaborated with top universities in China.
