Google Pay Tube Challenge is an in-app digital experience developed in partnership with Transport for London (TfL). Android users who tap for their train rides using Google Pay can collect digital badges, learn about the history of stations, and earn raffle entries for a chance to win prizes.

Google Pay’s illustration style is delightful and airy, focusing on the subject with minimal detail and simplified features.

As a Product Illustrator on the Google Pay UX team, I contributed to the expansion of a scalable illustration system across Google Pay and Wallet. Collaborating with cross-functional stakeholders, I created vector icons, spot illustrations, and hero visuals used across key digital touchpoints, including onboarding flows, product launches, and marketing campaigns. During my time on the team, I produced over 50 final vector assets, helping unify the brand and product experience while amplifying Google Pay’s visual identity.
