Building a web application begins with outlining user roles, key use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to ship rapidly without becoming a fragile collection of isolated screens.

Once launched, scalability and reliability take precedence: performance budgets, caching strategies, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and a well-considered architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
