Web application development begins with outlining user roles, essential scenarios, and the data structure. A solid MVP emphasizes main workflows, intuitive navigation, and consistent UI components, so the product can be delivered rapidly without becoming a fragile collection of bespoke screens.

After launch, scalability and reliability take precedence: performance budgets, caching strategies, secure authentication, and well-defined API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
