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

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, strong authentication, and tidy API agreements. Through effective monitoring, CI/CD pipelines, and well-considered architecture, groups can iterate more rapidly while preserving codebase stability as features and traffic increase.
