Hi, I’m Ruihai (ray-hi), a lead product designer who makes it easy to find useful data in complex systems. I research to create alignment, test to reduce risk, and design to ship fast.

At Flatiron Health I’m building PCE, an LLM tool that allows anyone with clinical knowledge to extract and structure patient chart data. PCE builds on my ML tooling experiments, including AI-generated patient summaries and copy paste detection, to help scale our data.

Earlier at Flatiron, I overhauled patient selection so researchers can create complex cohorts with confidence.

Previously, I was at Aperture Health, where I used service design to improve their credentialing workflow and eliminate thousands of hours of waiting time. At VMware, I helped the FAA translate airspace data into useful information for pilots amongst other consulting projects.

As a full-stack designer, I’ve done everything from greenfield research to design systems. I specialize in lean experimentation and content-first prototyping to derisk assumptions and launch products faster. I’m constantly focused on shipping the right thing to users quickly and working closely with PMs and engineers to do so.

I grew up in France and moved to the United States in 2017. Outside work, find me drawing, biking across DC, reviewing coffee, and fostering cats.
