Web app development begins by outlining user roles, essential use cases, and the data schema. A robust MVP emphasizes core flows, intuitive navigation, and consistent UI components, enabling a fast release without becoming a brittle collection of ad hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, secure authentication, and well-defined API contracts. With effective monitoring, continuous integration and deployment, and careful system design, teams can iterate rapidly while preserving codebase stability as features and traffic increase.
