Building a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of tailored screens.

Post-launch, scalability and dependability take priority: performance constraints, caching strategies, robust authentication, and clean API interfaces. With solid monitoring, CI/CD pipelines, and deliberate architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
