Creating a web app begins with outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on main workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch priorities are scalability and reliability: performance budgets, caching, secure login, and clear API contracts. With appropriate monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic increase.
