Building a web app begins by outlining user roles, essential scenarios, and the data structure. A strong MVP concentrates on core pathways, intuitive navigation, and consistent UI elements, enabling the product to launch rapidly without becoming a fragile collection of ad-hoc screens.

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