Creating a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP emphasizes essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, the focus shifts to scalability and reliability: performance budgets, caching, secure login, and clean API agreements. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
