Building a web application begins by outlining user roles, essential use cases, and the data schema. A solid MVP emphasizes core workflows, intuitive navigation, and consistent UI elements, enabling a launchable product without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take center stage: performance budgets, caching, robust authentication, and tidy API contracts. By implementing proper monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
