Building a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP centers on essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of bespoke screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, robust authentication, and well-defined API contracts. With effective monitoring, CI/CD practices, and a well-considered architecture, teams can iterate quickly while maintaining codebase stability as features and demand expand.
