Building a web app begins by outlining user roles, essential scenarios, and the data model. A strong MVP targets the main workflows, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a fragile collection of ad hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clear API contracts. Through effective monitoring, CI/CD, and well-planned architecture, teams can move faster while maintaining codebase stability as features and traffic expand.
