Building a web application begins with outlining user roles, primary use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can go to market quickly without becoming a fragile collection of ad hoc screens.

Post-launch, scalability and dependability 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.
