Web application development starts with outlining user roles, key scenarios, and the data model. An effective MVP emphasizes core flows, intuitive navigation, and predictable UI components so the product can ship rapidly without turning into a fragile collection of one-off screens.

After 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 faster while keeping the codebase stable as features and traffic grow.
