Building a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on main workflows, 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, robust authentication, and clean API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate quickly while preserving codebase stability as features and traffic expand.
