Yosi Montes de Oca
UX Designer
I’m Yosi, a UX designer with over 3 years of experience based in New York City. I began my career as an architect and later transitioned into UX after earning a master’s in Human-Computer Interaction. Today, I lead the design experience for accounts, permissions, and billing across Amazon Ads.
Select works
Promotions page for billing center
As the design lead, I created the end-to-end Promotions Page experience for the Sponsored Ads Billing Center. The goal was to make promotional credits easy to discover, understand, and redeem, while bringing clarity to a system that previously lacked cohesion. The final experience introduced a structured information model, clearer eligibility rules, and a simplified way for advertisers to track and apply their promotion benefits.
Single global advertiser account
In 2025, Amazon Ads introduced a new account type that unified Sponsored Ads and Amazon DSP within a single account. The project involved designing a flexible permissions system for various user roles, creating a new user invitation flow, and launching a dedicated registration experience — enabling teams to onboard and collaborate more effectively from day one.
DSP Creative Gallery
In 2024, Amazon DSP launched the new Creative Gallery — a redesigned experience that helps advertisers discover and select the right creative formats for their campaign goals. This release simplified a complex system, introduced new ad experiences, and brought visual clarity to a once-fragmented workflow.
Vetting Center
The Vetting Center is a feature launched in 2025 that allows advertisers to verify their business information and apply to advertise in regulated product categories requiring special permissions, such as pharmaceuticals, political advertising, and gaming.
Other Initiatives I Helped Bring to Life
Since joining Amazon Ads, I have contributed to more than 100 projects as a design lead and collaborator. Working across multiple product areas has helped me become a more holistic and systems-oriented designer. Below are a few initiatives I have helped bring to life, all of which are live across Amazon Ads.
Design Lead
