Building a web application begins by identifying user roles, main use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling the product to launch swiftly without becoming a brittle collection of ad-hoc pages.

Post-launch, scalability and reliability are paramount: performance budgets, caching, secure authentication, and well-defined API contracts. With effective monitoring, CI/CD practices, and deliberate architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
