Building a web application begins by outlining user roles, essential use cases, and the data structure. A robust MVP concentrates on the main flows, intuitive navigation, and consistent UI elements, allowing the product to launch swiftly without deteriorating into a fragile collection of ad-hoc screens.

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