Building a web application begins by outlining user roles, main use cases, and the data structure. A robust MVP concentrates on 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 take priority: performance budgets, caching, strong authentication, and clean API boundaries. With adequate monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining code stability as features and traffic increase.
