Building a web application begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on primary flows, intuitive navigation, and consistent UI elements, enabling fast 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 effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
