Web application development begins by identifying user roles, essential scenarios, and the data model. A solid MVP concentrates on core flows, clear navigation, and dependable UI components, so the product can launch swiftly without becoming a fragile set of one-off screens.

After launch, scalability and reliability take precedence: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
