Building a web app begins by outlining user roles, essential use cases, and the data structure. A robust MVP concentrates on main flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, secure sign-in, and clean API schemas. Through effective monitoring, automated deployment pipelines, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
