Building a web application begins by outlining user roles, essential use cases, and the data schema. A strong MVP concentrates on the main trajectories, intuitive navigation, and consistent UI elements, enabling a fast release without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance ceilings, caching strategies, secure login, and tidy API agreements. With adequate observability, CI/CD pipelines, and well-considered architecture, teams can move faster while maintaining a stable codebase as capabilities and traffic expand.
