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

Post-launch, scalability and dependability take precedence: performance budgets, caching, strong authentication, and tidy API interfaces. With solid monitoring, CI/CD, and careful architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic expand.
