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

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