Developing a web application begins with defining user roles, primary use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and predictable UI elements, enabling the product to ship rapidly without becoming a fragile collection of ad-hoc screens.

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