Building a web application begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on core paths, intuitive navigation, and consistent UI elements, so the product can launch swiftly without becoming a fragile collection of ad-hoc screens.

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