Web application development begins with outlining user roles, key scenarios, and the data structure. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can launch quickly without turning into a fragile set of one-off screens.

After launch, scalability and reliability 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 grow.
