Building a web app begins with outlining user roles, main use cases, and the data structure. A strong MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a brittle collection of bespoke screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, secure login, and clean API contracts. Through adequate monitoring, CI/CD, and deliberate architecture, teams can iterate swiftly while maintaining codebase stability as features and user demand expand.
