Building a web application begins by outlining user roles, key scenarios, and the data model. A solid MVP emphasizes essential flows, intuitive navigation, and consistent UI components, enabling the product to ship rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more quickly while preserving a stable codebase as features and traffic increase.
