Hi, I'm Jin
I started as a designer, became a frontend engineer, and now build products end to end, from the first sketch to the App Store. Most recently I worked on the frontend core team at ComfyUI, the open-source generative AI platform, owning its Design System and Node Manager. I also designed, built and shipped my own dog-care app, PoopieMate, on iOS and Android. I care less about screens that look nice and more about screens people never hesitate on.
