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

Post-launch, scalability and reliability take priority: performance budgets, caching, secure authentication, and clean API contracts. With solid monitoring, CI/CD, and deliberate architecture, teams can iterate more rapidly while maintaining codebase stability as features and traffic expand.
