Creating a web application begins with outlining user roles, primary scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can ship rapidly without becoming a fragile collection of custom screens.

Post-launch, scale and reliability take precedence: performance budgets, caching, secure sign-in, and clean API contracts. With proper monitoring, CI/CD, and well-thought architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic grow.
