Building a web application begins with defining user roles, primary scenarios, and the data model. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI components, enabling the product to ship quickly without becoming a fragile collection of bespoke screens.

After launch, performance, scalability, and reliability become the priorities: budgets for performance, caching, secure sign-in, and clean API contracts. With proper monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
