Creating a web app begins by 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 isolated pages.

Post-launch, scalability and dependability take priority: performance ceilings, caching strategies, robust authentication, and clear API definitions. With effective monitoring, continuous integration/delivery, and well-planned architecture, teams can improve quickly while preserving code stability as features and traffic expand.
