Building a web app begins with identifying user roles, essential use cases, and the data structure. A strong MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling a fast release without becoming a brittle collection of ad-hoc pages.

Post-launch, scalability and dependability take priority: performance constraints, caching, secure login, and clear API agreements. With proper observability, CI/CD, and careful architecture, teams can iterate more quickly while preserving code stability as capabilities and traffic expand.
