Building a web application begins by outlining user roles, essential scenarios, and the data structure. A robust MVP concentrates on primary flows, intuitive navigation, and consistent UI elements, enabling the product to launch rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scale and dependability are paramount: performance budgets, caching, secure authentication, and tidy API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
