Building a web application begins by outlining user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling a fast launch without becoming a fragile collection of bespoke screens.

Once released, scalability and reliability become the top priorities: performance budgets, caching, strong authentication, and clean API contracts. With proper monitoring, CI/CD pipelines, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
