Web application development begins with identifying user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, so the product can be released quickly without becoming a fragile collection of ad-hoc screens.

After launch, scalability and reliability are paramount: performance budgets, caching strategies, secure authentication, and clean API contracts. With proper monitoring, CI/CD practices, and thoughtful architecture, teams can iterate faster while preserving the codebase’s stability as features and traffic grow.
