Building a web application begins with outlining user roles, main scenarios, and the data model. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling rapid delivery without becoming a fragile collection of piecemeal screens.

After launch, performance, scalability, and reliability take precedence: budgets for performance, caching strategies, secure login, and clean API contracts. With proper monitoring, continuous integration and deployment, and a thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic expand.
