Building a web application begins by outlining user roles, essential scenarios, and the data model. An effective MVP concentrates on core workflows, intuitive navigation, and consistent UI elements, enabling the product to ship rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability take precedence: performance budgets, caching strategies, secure authentication, and clean API contracts. With proper monitoring, CI/CD practices, and a well-considered architecture, teams can iterate more quickly while maintaining a stable codebase as features and traffic expand.
