Web application development begins with outlining user roles, key scenarios, and the data model. A solid MVP emphasizes core flows, clear navigation, and consistent UI components, enabling rapid delivery without turning into a fragile collection of ad-hoc screens.

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