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

Post-launch, scalability and dependability are paramount: performance targets, caching strategies, secure sign-in, and clear API contracts. With adequate observability, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
