Let's connect()
I was trained as an engineer in South Korea, but I was always drawn to architecture, not buildings, but the invisible kind that shapes how people experience the world.
That curiosity led me to product design, where I could combine technical thinking with human-centered craft. After earning my master's in HCI at UC Berkeley, I designed complex enterprise products at Oracle and later led design teams at Atlassian across Confluence and Trello.
Today at Rippling, I lead product design while staying deeply hands-on, designing systems, shipping production code with AI, and building 0→1 products that power modern companies.
I am motivated by building the foundations behind great products, so teams can move faster and people can use technology with clarity and confidence.
Outside of work, I run regularly, documenting my distance and routes in a running diary on Instagram. I also collaborate on side projects, building productivity tools that turn ideas into practical solutions. See my other projects.
