Don’t let your backend write checks your frontend can’t cache

Frontend and backend architecture must work in harmony to deliver performant user experiences. As AI-generated interfaces and ephemeral UIs emerge, backend systems face new challenges around API orchestration, caching, and performance at scale. Frontend engineers need to understand backend constraints like processing load, API response times, and scalability to avoid creating interfaces that promise more than the backend can deliver. The shift toward component-based, modular interfaces requires spec-driven design and careful consideration of how APIs are structured and consumed. While AI can accelerate development, production-grade systems still require human understanding and ownership of both frontend and backend code.
