Building a web application begins with defining user roles, key use cases, and the data model. An effective MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can launch swiftly without becoming a fragile collection of one-off screens.

After launch, scalability and reliability are paramount: 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 expand.
