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

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure authentication, and clear API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining a stable codebase as features and traffic expand.
