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

Post-launch, scalability and dependability take the lead: performance budgets, caching strategies, safe authentication, and clean API contracts. With solid monitoring, CI/CD practices, and deliberate architecture, teams can move faster while preserving code stability as features and traffic expand.
