Creating a web application begins by outlining user roles, main use cases, and the data structure. A solid MVP focuses on core workflows, consistent UI elements, and predictable navigation, so the product can be released rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability take precedence: performance budgets, caching, robust authentication, and well-defined API contracts. With solid monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
