Building a web application begins with defining user roles, essential scenarios, and the data model. A strong MVP concentrates on the main flows, intuitive navigation, and consistent UI elements, enabling the product to ship rapidly without becoming a brittle collection of scattered screens.

Once deployed, scalability and reliability take center stage: performance budgets, caching, robust 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.
