Web application development begins by outlining user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, so the product can be delivered quickly without turning into a brittle collection of isolated 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 expand.
