Building a web app begins by outlining user roles, main use cases, and the data structure. A strong MVP concentrates on essential workflows, straightforward navigation, and consistent UI elements, enabling a release without becoming a brittle collection of ad-hoc screens.

Post-launch, scale and dependability take precedence: performance budgets, caching strategies, secure logins, and tidy API definitions. With adequate monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving code stability as features and demand expand.
