Creating a web application begins by outlining user roles, primary scenarios, and the data model. A strong MVP concentrates on essential flows, straightforward navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability take precedence: performance budgets, caching, secure authentication, and clean API contracts. With solid monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic increase.
