Building a web application begins with outlining user roles, primary use cases, and the data structure. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, so the product can be delivered quickly without becoming a fragile collection of ad-hoc screens.

After launch, scalability and reliability take precedence: performance budgets, caching, robust authentication, and tidy API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
