Building a web app begins by outlining user roles, primary use cases, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without morphing into a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure sign-in, and clean API agreements. With solid monitoring, CI/CD, and well-considered architecture, teams can iterate swiftly while maintaining code stability as features and traffic expand.
