Creating a web application begins by outlining user roles, main use cases, and the data structure. A strong MVP emphasizes essential paths, intuitive navigation, and dependable UI elements, enabling the product to launch rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, the priority is scalability and reliability: performance ceilings, caching, robust authentication, and clean API interfaces. Through vigilant monitoring, CI/CD practices, and well-planned architecture, teams can iterate quickly while preserving codebase stability as features and user demand increase.
