Building a web application starts by outlining user roles, key use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling the product to ship rapidly without turning into a brittle collection of ad-hoc screens.

Once launched, the priorities shift to scalability and dependability: meeting performance budgets, caching strategies, secure login, and clean API boundaries. With solid monitoring, CI/CD, and careful architecture, teams can push iterations faster while keeping the codebase stable as features and traffic grow.
