Creating a web application begins with defining user roles, key scenarios, and the data model. A strong MVP prioritizes essential flows, intuitive navigation, and consistent UI components, enabling the product to ship quickly without becoming a brittle collection of disjoint screens.

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