Building a web application begins by outlining user roles, main use cases, and the data structure. A solid MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a fragile collection of ad hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, robust authentication, and clean API contracts. Through solid monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
