Web application development begins by outlining user roles, essential use cases, and the data structure. A solid MVP concentrates on core flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without transforming into a fragile set of ad-hoc screens.

After launch, scalability and reliability become paramount: performance budgets, caching strategies, secure authentication, and well-defined API interfaces. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and demand grow.
