Building a web app begins by outlining user roles, essential scenarios, and the data structure. An effective MVP concentrates on main flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clean API contracts. With solid monitoring, CI/CD practices, and well-planned architecture, teams can iterate more quickly while preserving code stability as features and user load expand.
