Creating a web application starts with identifying user roles, key use cases, and the data model. A solid MVP emphasizes essential flows, intuitive navigation, and consistent UI components, so the product can ship rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, performance, scalability, and reliability are priorities: budgeted performance targets, caching, secure login, and clean API contracts. With proper observability, CI/CD, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic grow.
