Building a web app begins by outlining user roles, main scenarios, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling 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 authentication, and tidy API contracts. With effective monitoring, CI/CD, and well-designed architecture, teams can iterate more rapidly while maintaining codebase stability as features and traffic expand.
