Beginning a web application involves outlining user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling rapid delivery without turning into a fragile collection of one-off screens.

After launch, scalability and reliability are the priority: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic expand.
