Experience
Uber Eats Messaging
I led the mobile implementation of the Uber Eats messaging platform in the tech lead capacity. This project enabled product teams at Uber to display contextual messaging on several in-app surfaces in Uber Eats.
Teams could drive promotional and upsell campaigns and experiment on several dimensions, such as message placement, UI presentation format, and prioritization. This platform streamlined in-app messaging by unifying the implementation across over ten different surfaces in the app.
The time to implement a new messaging surface went down from over a month to one week. This platform increased the order conversion rate by over 1%, resulting in millions of dollars in additional revenue for Uber Eats.

Uber Credit Card
On this project, I directed the mobile development of the Uber Credit Card. This innovative financial product enabled riders to apply for a credit card in under a minute directly inside the Uber app. Approved users would have a virtual credit card added to their app immediately, which they could use to take Uber rides and earn rewards. The product leveraged the user's information to prescreen for approval probability and pre-filled the application form with available data.
I led the architecture and design of the feature on iOS, including the encryption of user details and back-end APIs. The credit card was one of Uber's few revenue-generating products at the time. Over one hundred thousand cards were issued, and many new users were brought into the Uber app to apply for the card.
