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

Post-launch, scalability and dependability take priority: performance budgets, caching, secure login, and tidy API agreements. With effective monitoring, CI/CD, and well-designed architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
