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

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure authentication, and clean API contracts. With adequate monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic expand.
