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

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