Building a web application begins by outlining user roles, main use cases, and the data schema. A strong MVP emphasizes essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure login, and clean API interfaces. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate quickly while preserving codebase stability as features and user demand expand.
