Building a web app begins by outlining user roles, main scenarios, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling the product to ship rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, robust authentication, and clear API contracts. With adequate monitoring, CI/CD, and well-considered architecture, teams can iterate quicker while maintaining codebase stability as features and traffic expand.
