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

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure login, and tidy API boundaries. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
