Jeewoon Lee
Senior Product Designer @ McKinsey & Company
I'm a product designer based in New York, currently working on AI-assisted tools and enterprise software.
I'm interested in finding what good interaction looks like, how trust gets built, and how to help people use AI tools well and often.
Outside of work, I like to build small experiments and write on Substack about design, technology, and craft.
