Building web applications begins with outlining user roles, key use cases, and the data schema. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can ship quickly without becoming a fragile collection of ad-hoc screens.

After launch, scalability and reliability are paramount: performance budgets, caching, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
