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

Post-launch, scalability and dependability take priority: performance budgets, caching, robust authentication, and well-defined API contracts. With adequate monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
