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

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, robust authentication, and clean API interfaces. With effective monitoring, continuous integration/delivery, and well-considered architecture, teams can iterate more swiftly while preserving codebase stability as features and traffic expand.
