Building a web app begins by outlining user roles, main use cases, and the data structure. A well-crafted MVP emphasizes essential workflows, 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 clean API agreements. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
