Shared Payments

Sandra Jurek describes how Chase UK organized its React Native app around product features after a large shared package structure became difficult to maintain. She explains how excessive package splitting increased cyclic dependencies, release coordination, and uncertainty about ownership. Feature-driven design groups flows and utilities by the product areas they serve, making code ownership clearer and shared functionality easier to place. Jurek says this approach reduced package relationships, improved teams’ independence, and gave developers and product owners a common language.
