Building a web app begins with outlining user roles, essential scenarios, and the data structure. A strong MVP concentrates on essential workflows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of ad-hoc screens.

Post-launch, scale and dependability take priority: performance budgets, caching, robust authentication, and clean API interfaces. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate quicker while preserving codebase stability as features and traffic increase.
