Building a web app begins by clarifying user roles, main use cases, and the data structure. A robust MVP concentrates on essential flows, intuitive navigation, and reliable UI components, enabling a fast release without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance targets, caching strategies, secure logins, and well-defined API contracts. With effective monitoring, CI/CD practices, and a well-planned architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
