Product Designer & Business Owner · Santa Clara, CA
Hi, I'm Jongmi Bae.
I'm a product designer in Santa Clara, California — most people call me Jamie. I design digital products that are engaging, functional, and accessible — and I run JTL Hub, an e-commerce business. My background spans fine art, interaction design, and end-to-end product work, from early research to polished UI.
