Building a web application begins with defining user roles, primary use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling the product to ship rapidly without turning into a fragile collection of one-off screens.

After launch, 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.
