Web application development starts with defining user roles, essential scenarios, and the data model. A strong MVP highlights the core flows, intuitive navigation, and consistent UI components, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Following launch, performance and reliability take precedence: budgets for performance, caching strategies, secure authentication, and clean API contracts. With solid monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
