Creating a web application begins by outlining user roles, primary use cases, and the data structure. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling fast delivery without becoming a fragile collection of custom screens.

Post-launch, scalability and reliability take precedence: performance budgets, caching, secure authentication, and clear API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
