Building a web application begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on main workflows, intuitive navigation, and consistent UI elements, letting the product launch rapidly without becoming a fragile collection of ad-hoc pages.

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