Building a web application begins by outlining user roles, essential use cases, and the data structure. A solid MVP emphasizes essential workflows, intuitive navigation, and consistent UI elements, enabling a fast release without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure authentication, and clean API boundaries. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic expand.
