How to deliver 3x faster with effective API design — Michal Cyprian

Backend for Frontend (BFF) pattern helps simplify client-server communication by creating dedicated backend endpoints for specific client needs

Server-driven UI allows controlling UI components from the backend through JSON data, reducing need for client-side implementation and enabling faster updates

Moving from triple implementation (iOS, Android, Web) to centralized backend control improves consistency across platforms and reduces development overhead

BFF layer enables building customized endpoints for specific client requirements while maintaining clean separation of concerns

Changes can be deployed immediately without requiring app store approvals since UI logic lives on the server

Performance optimizations achieved by reducing multiple REST calls to single BFF requests that aggregate needed data

Translation and localization handled on backend, sending ready-to-display content to clients

Iterative approach recommended - start with few endpoints, evaluate results, then expand based on learnings

Thin clients focused only on rendering components, with business logic moved to backend

Some tradeoffs include additional architectural complexity, need for careful API versioning, and potential overhead from extra service layer
