Building a web app begins by outlining user roles, essential use cases, and the data schema. A strong MVP centers on main workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc pages.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure login, and well-defined API boundaries. With effective monitoring, CI/CD practices, and deliberate architecture, teams can move quickly while maintaining a stable codebase as features expand and traffic rises.
