Stripe Manual Payments

This summer, I joined Stripe as a Product Design Intern, shipping a full redesign of Manually Entered Card Payments, a merchant-facing workflow serving 60, 000+ monthly users. I partnered with engineering, product, research, and content to uncover high-impact opportunities and shape solutions around user needs and business goals.

Role

Product Design Intern

Timeframe

Summer 2026, 3 Months

Team

1 PM, 3 Engineers, 1 Content Design

Long Story Short

I redesigned a Stripe payment experience processing $21M everyday

I took ownership of a dated, high-traffic area of the Stripe Dashboard with limited direction and significant opportunity for impact. I rebuilt the experience using Sail, Stripe’s design system, bringing it in line with modern product standards.

Discover

Scoped an ambiguous problem space by analyzing recurring support issues, mapping existing friction, and defining the merchant journey.

Research

Owned an end-to-end research study with six interviews, translating user feedback into improvements across the product experience.

Design

Built prototypes and modular components to rapidly explore concepts, align with XFN partners, and accelerate implementation.

Thank you Stripe for an unforgettable summer ⊹ ࣪ ˖

Manual payments was a fascinating problem space and I’m so grateful I was trusted to contribute to it. A huge thank you to my manager Ian, and my team for taking a chance on me. I feel very lucky to have been a part of such a special place.
