Web application development begins by outlining user roles, essential scenarios, and the data model. A strong MVP concentrates on core flows, intuitive navigation, and consistent UI components, enabling the product to ship rapidly without becoming a brittle collection of standalone screens.

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