Creating a web application begins with outlining user roles, key use cases, and the data model. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Following launch, scalability and reliability are paramount: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and a thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
