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

Post-launch, scalability and reliability take precedence: performance budgets, caching, secure login, and well-defined API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
