Building a web app begins by outlining user roles, essential scenarios, and the data structure. A robust MVP concentrates on main workflows, straightforward navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are top priorities: performance budgets, caching strategies, strong authentication, and tidy API interfaces. With effective monitoring, CI/CD practices, and careful architecture, teams can accelerate iteration while preserving codebase stability as features and traffic expand.
