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

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure sign-in, and clean API agreements. With adequate observability, CI/CD, and careful architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
