Worked on the stripe-android repository to expand payment method flexibility in the Link wallet by introducing a Generic payment method type. This involved enabling server-driven rendering for unrecognized payment methods using Kotlin and Android UI development, removing hardcoded filtering, and adding edit flows for Generic payment methods. Enhanced the wallet’s resilience by implementing polling after redirects and passing all funding sources to the backend. Improved quality through expanded unit and screenshot test coverage, updated localization assets, and UI polish. The work focused on robust API integration and unit testing, ensuring the wallet can adapt smoothly to new payment types in production.
