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

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, robust authentication, and clean API contracts. With adequate monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
