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

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, strong authentication, and clear API contracts. Through effective monitoring, CI/CD, and careful architecture, teams can iterate quicker while maintaining codebase stability as features expand and traffic increases.
