Web application development begins with outlining user roles, main use cases, and the data model. A solid MVP concentrates on essential workflows, intuitive navigation, and consistent UI elements, so the product can be delivered rapidly without becoming a brittle collection of ad-hoc screens.

After launch, scalability and reliability take priority: performance budgets, caching strategies, robust authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more quickly while maintaining code stability as features and traffic grow.
