Building a web application begins by outlining user roles, essential scenarios, and the data structure. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scale and dependability are paramount: performance budgets, caching, secure login, and clean API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate faster while maintaining codebase stability as features and traffic expand.
