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

Post-launch, scalability and dependability are paramount: performance budgets, caching, secure login, and clean API agreements. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and user load expand.
