Building a web app begins by outlining user roles, main use cases, and the data schema. A strong MVP concentrates on essential paths, intuitive navigation, and reliable UI elements, enabling a rapid release without becoming a brittle collection of isolated screens.

Post-launch, scalability and dependability take priority: performance targets, caching strategies, secure login, and well-defined API interfaces. Through solid monitoring, CI/CD practices, and careful architecture, teams can iterate more quickly while maintaining code stability as features and user demand expand.
