Building a web application begins by outlining user roles, primary use cases, and the data schema. A robust MVP concentrates on essential workflows, intuitive navigation, and consistent UI elements, allowing the product to launch swiftly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure login, and clean API interfaces. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more rapidly while maintaining codebase stability as features and traffic expand.
