Creating a web application starts by outlining user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can be shipped rapidly without turning into a fragile collection of custom screens.

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