Building a web application begins by outlining user roles, primary use cases, and the data structure. A robust MVP emphasizes essential paths, intuitive navigation, and reliable UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching, secure sign-in, and tidy API agreements. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
