Monthly BNPL Installments for Major Retailer Credit Card
“This project was heavy—Kate helped us stay light without losing focus.”
Product Overview
Apple wanted to offer interest-free installment payments for big-ticket device purchases through an exciting new credit card. I joined as an embedded product manager and coach, supporting the backend team through build, test, and launch - helping a Big Bank and Pivotal engineers deliver secure, scalable services behind a flagship financial feature.
- Delivered backend APIs to support monthly credit card installments
- Defined and validated service behaviors using Postman and user flow walkthroughs
- Coached engineering teams on user-centered delivery and fast feedback loops
- Strengthened collaboration between Banks, Processors, and Digital teams
- Brought levity and cohesion to a secretive, high-stakes project (including a custom launch trivia game!)
Product Goals
How might we build installment services that meet the rigor of financial compliance - and still feel as seamless as a major stylish retailer should?
This was a cross-institutional dance between UX expectations, legal obligations, and service scalability. My goal was to make sure the backend team could ship confidently in this high-pressure environment, with clarity, alignment, and space for human collaboration.
- Prioritized lean service architecture with adaptability for future devices and terms
- Advocated for clear service outcomes over technical output

Challenges

- Delivering within high-stakes security and compliance requirements
- Navigating shifting priorities across backend services, device timelines, and UX dependencies
- Maintaining team morale on a tight, secretive, and highly scrutinized initiative
Solutions
- Developed clear validation and alignment strategies using API specs and testing protocols
- Led backend delivery planning using service maps and outcome-first user stories
- Provided embedded coaching and async rituals to support team velocity
- Introduced a balance of structure and play to keep energy high under pressure
Outcome & Impact
