Hello again.

About Me.

Hi, I’m Yoomi. I’m a Principal Product Designer with 15+ years of experience creating thoughtful, user-centered digital products across a wide range of industries. I was born in Japan, raised around the world, and kicked off my design career in New York City as a multimedia designer. After a five-year detour in Los Angeles, I’m now back in NYC—where everything just feels (and tastes) better.

I spent my early years in NYC working as a Creative Director and Senior UI/UX Designer at three different software agencies. I led design efforts for clients ranging from small local businesses to large financial institutions—translating complex needs into clear, scalable, and intuitive digital experiences.

In LA, I joined a B2B wholesale fashion marketplace as the Principal UI/UX Designer. I led the design of the platform’s admin tools, helping vendors and retailers manage inventory, onboard smoothly, and transact efficiently.

Currently, I’m a Principal Product Designer at Roofstock, where I focus on building an Enterprise application that supports the full MLS disposition workflow. The tool helps sellers, agents, and internal teams track, manage, and communicate through every stage of the sales process—from onboarding and pricing to offers, negotiations, and final closing. It’s deeply collaborative, operationally critical work, and I genuinely enjoy designing systems that make complex processes feel seamless and clear.

I bring a systems-thinking mindset, cross-functional collaboration skills, and a sharp eye for execution to every project. My goal is to design tools that not only look good—but actually make people’s work better, faster, and a little more enjoyable.

I have worked with Yoomi for over five years, through several companies, including hectic and demanding start-ups. Through our engagement, Yoomi has lead a rebrand for an established luxury health club, created IR collateral development for a technology startup, and has created visual assets for multiple digital campaigns. Yoomi's work is not only impeccable, but she delivers it quickly, with minimal unnecessary back and forth, and always with a smile. I couldn't recommend Yoomi's work product and work ethic enough!

Yoomi has an excellent eye for detail. She is a very hard worker and sticks to deadlines at all times. She enjoys what she does and it is reflected in her work, which is top quality.

Working with Yoomi is like having a second brain doing entirely different things but in sync. Her UX approach is technical as well as fundamentally sound and creative. She is an effective and objective leader - excels at optimizing and getting results when chaos is thrown at her.
