Creating a web application begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling the product to launch swiftly without evolving into a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability take precedence: performance budgets, caching strategies, secure authentication, and well-defined API contracts. With solid monitoring, CI/CD, and deliberate architecture, teams can iterate more rapidly while maintaining codebase stability as features and user demand expand.
