Building a web application begins by outlining user roles, essential use cases, and the data structure. A solid MVP concentrates on primary workflows, intuitive navigation, and consistent UI elements, enabling a rapid release without evolving into a fragile collection of ad-hoc screens.

Post-launch priorities shift to scalability and dependability: setting performance budgets, caching strategies, robust authentication, and clean API boundaries. With effective monitoring, CI/CD pipelines, and well-considered architecture, teams can iterate rapidly while maintaining codebase stability as features and traffic expand.
