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

Post-launch, the priority is scalability and dependability: performance budgets, caching strategies, robust authentication, and well-defined API contracts. Through effective monitoring, CI/CD practices, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and user demand expand.
