Creating a web application begins with defining user roles, principal scenarios, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling the product to ship quickly without becoming a fragile collection of bespoke screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic grow.
