Building a web application begins by outlining user roles, essential scenarios, and the data model. A strong MVP emphasizes the main workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc pages.

Post-launch, scalability and dependability are top priorities: performance budgets, caching, robust authentication, and clean API contracts. With proper monitoring, CI/CD, and well-considered architecture, teams can move faster while preserving a stable codebase as features and traffic expand.
