Building a web app begins by outlining user roles, essential scenarios, and the data schema. A strong MVP concentrates on primary flows, intuitive navigation, and consistent UI components, 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 login, and clean API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate faster while maintaining codebase stability as features and traffic expand.
