Creating a web app begins by outlining user roles, primary use cases, and the data structure. A robust MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a fragile collection of ad hoc screens.

Post-launch, scalability and reliability take priority: performance targets, caching strategies, secure login, and clean API boundaries. With adequate observability, CI/CD pipelines, and well-planned architecture, teams can iterate rapidly while preserving code quality as features and traffic expand.
