Building a web application begins by outlining user roles, essential scenarios, and the data structure. A strong MVP emphasizes core paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without a collection of fragile, one-off screens.

Post-launch, scale and dependability are the priority: performance budgets, caching strategies, secure login, and clean API contracts. With appropriate monitoring, CI/CD pipelines, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
