Building a web app begins by outlining user roles, primary use cases, and the data structure. An effective MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling fast delivery without devolving into a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, robust authentication, and solid API contracts. By implementing proper monitoring, CI/CD, and well-designed architecture, teams can iterate more rapidly while maintaining codebase stability as features and traffic expand.
