Building a web application begins by outlining user roles, primary use cases, and the data structure. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of ad hoc screens.

Post-launch, scalability and dependability take center stage: performance budgets, caching strategies, safe authentication, and clear API interfaces. With effective monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving code stability as features and traffic expand.
