Hi, I'm Fangchi.
I'm a product data scientist based in San Francisco. I currently work on analytics for safety and integrity systems, where tech operates at scale while human judgment remains essential. I'm curious about how we measure and evaluate complex autonomous systems broadly, where defining success is part of the optimization process.
I grew up in Beijing and studied in Shenzhen and New York. Outside of work, I enjoy climbing without pushing grades, baking, crocheting, walking through parks, meditation, and films by Wong Kar-wai.
I keep this site as a practice ground for collecting things I build, learn, and notice, and to practice living more mindfully.
