Web app development begins by establishing user roles, essential scenarios, and the data model. A robust MVP concentrates on primary flows, intuitive navigation, and dependable UI elements, ensuring the product ships rapidly rather than becoming a fragile collection of ad hoc screens.

Following deployment, scalability and reliability are paramount: performance budgets, caching, strong authentication, and clean API contracts. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
