Web application development begins by outlining user roles, primary scenarios, and the data model. An effective MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling rapid shipping without becoming a brittle collection of one-off screens.

Post-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.
