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

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure authentication, and clean API contracts. With appropriate monitoring, CI/CD, and thoughtful architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
