Building a web application begins by outlining user roles, main scenarios, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a fragile collection of ad hoc screens.

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