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

Post-launch, growth and dependability take precedence: performance budgets, caching strategies, robust authentication, and clear API contracts. With solid monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as capabilities and traffic expand.
