Creating a web application begins by outlining user roles, essential scenarios, and the data model. A solid MVP concentrates on core flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability are paramount: performance budgets, caching, robust authentication, and clean API contracts. With effective monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more quickly while preserving a stable codebase as features and traffic expand.
