Building a web app begins by outlining user roles, main scenarios, and the data structure. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are priority: performance budgets, caching strategies, secure login, and clean API interfaces. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while maintaining code stability as features and traffic rise.
