About Yueyi Cheng

Hello there! I\'m a Software Engineer at Google, kinda obsessed with making \"health as a right\" a real thing using cool AI stuff, especially within Health Intelligence. I work on personal health agent AI, and right now, I\'m nerding out on LLM agent evaluation and super-fast AI/ML prototypes in the health space. When I\'m not coding, you\'ll find me mentoring STEM students or out in the community. What I geek out on: AI for Health Intelligence, LLM tasks, Java/Python, and keeping AI safe and sound. My mantra: Let\'s build tech that\'s super helpful, thinks about people first, and is easy for everyone to use. 🤝 Giving back: Helping the next gen of STEM stars find their way through mentorship and education. Basically, I love tech and helping people!
