Building a web application begins by outlining user roles, essential use cases, and the data structure. A robust MVP emphasizes core flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of isolated screens.

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