Web application development begins with specifying user roles, key scenarios, and the data model. A solid MVP concentrates on essential flows, straightforward navigation, and predictable UI components, so the product can be released quickly without becoming a fragile set of one-off screens.

After deployment, scalability and reliability become the top priorities: 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.
