Creating a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scale and dependability are the top priorities: performance budgets, caching strategies, robust authentication, and clean API definitions. With adequate monitoring, continuous integration/delivery, and a well-considered architecture, teams can iterate quickly while maintaining a stable codebase as features and traffic expand.
