Creating a web app begins by outlining user roles, primary use cases, and the data schema. A robust MVP emphasizes essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of isolated screens.

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching, strong authentication, and clear API agreements. Through effective monitoring, CI/CD pipelines, and well-considered architecture, teams can iterate more quickly while preserving codebase stability as features expand and traffic increases.
