Hello again.

About Me.

I’m Yoomi. I am a Principal-level Product Designer with over 15 years of experience across multiple industries. I was born in Japan, raised around the world, kicked off  my career in NYC as a multi-media designer, cheated on NYC between 2016-2021 and moved out to LA, but am back living/working in NYC where everything feels and tastes better. 

In my first 10 years in NYC, I worked as a Creative Director / Sr. UI/UX across 3 different software agencies. Industries varied from small mom-and-pop shops to enterprise-level financial services. 

In LA, I worked on a B2B Wholesale Fashion Marketplace as a principal UI/UX Designer. I was in charge of the admin system implementing wholesalers vendors and retailers experiences.

Currently, I work as a Senior Lead Product Designer at Roofstock. I am in charge of designing Enterprise applications for our Institutional Clients and Internal teams and I can sincerely tell you that it is… fun. I get to map from scratch how our Institutional sellers interact with our internal teams – a full end-to-end experience from onboarding to countering and finalizing their sales, monitoring the progress and communication between the brokers. On the flip side, I am creating a portal system that pulls all communications and transactions in milestones from our Underwriting teams, business development teams, brokers and buyers. A lot to cover but it’s just simply fun maximizing my thought process and building products from scratch.

Product Minded.

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.
