Building a web application begins by outlining user roles, essential scenarios, and the data structure. A strong MVP concentrates on the main flows, intuitive navigation, and consistent UI elements, enabling rapid release without turning the product into a brittle collection of bespoke screens.

Once released, performance, reliability, and scalability take priority: budgets for performance, caching, secure login, and clean API agreements. With proper observability, CI/CD, and thoughtful architecture, teams can iterate more quickly while preserving a stable codebase as features and traffic expand.
