Building a web app begins by outlining user roles, main use cases, and the data structure. A robust MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure login, and clean API agreements. Through effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while maintaining code stability as features and user demand expand.
