Building a web app begins by outlining user roles, main use cases, and the underlying data structure. A robust MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling the product to be released rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching strategies, secure authentication, and clean API contracts. Through effective monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
