Building a web application begins by outlining user roles, essential scenarios, and the data model. A robust MVP concentrates on main 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, secure sign-in, and clear API contracts. With effective monitoring, CI/CD pipelines, and well-planned architecture, teams can move faster while sustaining codebase stability as features and traffic increase.
