Crafting a web application begins with outlining user roles, key use cases, and the data model. A robust MVP prioritizes essential flows, clear navigation, and consistent UI components, so the product can be delivered quickly without turning into a fragile collection of one-off screens.

After launch, scalability and reliability take center stage: 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.
