Building a web app begins by outlining user roles, essential scenarios, and the data schema. A robust MVP concentrates on main flows, intuitive navigation, and reliable UI elements, allowing the product to launch swiftly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching, secure login, and clear API agreements. With effective monitoring, CI/CD pipelines, and well-considered architecture, teams can iterate rapidly while maintaining codebase stability as features and user demand expand.
