The Backend Carries Product Rules
Mobile and web interfaces should not be forced to reconstruct business logic from scattered endpoints. A dependable backend gives the product a single place for rules, permissions, validation, and long-running workflow decisions.
Design Around Boundaries
Good backend systems separate API contracts, domain behavior, persistence, integrations, and operational concerns. That separation makes change safer when the product adds new clients, user roles, or partner systems.
Build for Operation
A backend is not finished when endpoints return data. It needs logs, meaningful errors, deployment clarity, migration discipline, and documentation that lets the system be maintained with confidence.
