My responsibilities as a product designer include...

  • Design and deliver high-quality, user-centered solutions, including high-fidelity prototypes and specifications for new features and products.

  • Create end-to-end user experiences for global products, leading the design process from initial concepts and lo-fi wireframes to polished hi-fi mockups and interactive prototypes.

  • Collaborate with cross-functional teams like designers, product managers, content designers, accessibility, design researchers, and engineers to define and solve complex design problems.

  • Present and articulate design concepts to stakeholders while also mentoring and providing guidance to junior designers.

Affluent project

Context and challenge

Visa’s affluent cardholders have access to hundreds of premium benefits across travel, lifestyle, and dining — yet these experiences are often scattered across issuer channels, websites, and concierge services. According to Visa, affluent consumers represent one of the fastest-growing spending segments globally, driving three times more international travel spending than other consumer groups.


The design opportunity was to create a unified, user-centered digital experience that simplifies how affluent customers discover and access Visa’s premium benefits. The goal was to strengthen engagement by making high-value offerings more visible, personalized, and intuitive to explore.

Visa Flexible Credential

Context and challenge

Consumers increasingly expect payment flexibility: ability to use multiple funding sources, digital payment experiences, and simpler wallet management. 84% of users intend to use virtual accounts for flexible payments, and 51% users want streamlined access to multiple accounts. At the same time, issuing banks and fintech partners need scalable solutions that integrate into existing systems without overwhelming complexity.


The challenge: How might we enable a single payment credential to access multiple funding sources while preserving a seamless experience for both end-users and issuer systems?

Design approach

Setting a clear intended target audience for clear product direction and aligning with the business goals

Modular design approach demonstrating alignment between product value and user needs

Complexity tolerance by offering various levels of complexity in use cases to learn user preference and usability

Outcome and impact

  • The product launched in regions including APAC and is now being rolled out in the U.S. in partnership with issuers.

  • Early pilot data indicated that credential holders had ~40% higher spend than non-flex credential holders.

  • Issuers adopting the solution gained the ability to cross-sell more products under one credential and reduce management of multiple cards for customers.
