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

Post-launch, scale and dependability take priority: performance budgets, caching, secure authentication, and tidy API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving code stability as features and traffic increase.
