Web application development begins by outlining user roles, main scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, allowing the product to ship rapidly without becoming a fragile collection of ad-hoc screens.

After launch, scalability and reliability take precedence: performance budgets, caching, secure authentication, and clean API definitions. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving code stability as features and traffic expand.
