Web application development begins with outlining user roles, essential use cases, and the data schema. A robust MVP emphasizes core flows, straightforward navigation, and consistent UI components, so the product can be shipped rapidly without turning into a brittle collection of ad-hoc screens.

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