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

Post-launch, performance, scalability, and reliability take center stage: performance budgets, caching strategies, secure login, and well-defined API agreements. With effective monitoring, automated pipelines, and careful architecture, teams can iterate swiftly while maintaining a stable codebase as features and traffic expand.
