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

Post-launch, scalability and dependability take precedence: performance targets, caching strategies, secure login, and clear API interfaces. With effective monitoring, continuous integration/deployment, and well-considered architecture, teams can iterate more rapidly while preserving codebase stability as features and user demand expand.
