Building a web application begins by outlining user roles, essential scenarios, and the data model. A strong MVP concentrates on main workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of separate screens.

Post-launch, scalability and reliability take priority: performance budgets, caching, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
