Building a web app begins by identifying user roles, primary use cases, and the data structure. An effective MVP emphasizes essential workflows, straightforward 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, robust authentication, and clean API contracts. Through proper observability, CI/CD, and well-considered architecture, teams can move faster while maintaining codebase stability as features and traffic expand.
