Building a web app starts with outlining user roles, main use cases, and the data structure. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, so the product can ship quickly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure login, and well-defined API contracts. By implementing solid monitoring, continuous integration/deployment, and well-considered architecture, teams can move faster while maintaining code stability as features and traffic increase.
