Web application development begins with outlining user roles, essential scenarios, and the data structure. A robust MVP concentrates on core flows, intuitive navigation, and consistent UI components, so the product can launch rapidly without becoming a fragile collection of ad-hoc screens.

After launch, scalability and reliability take center stage: performance budgets, caching, secure authentication, and clean API interfaces. With effective observability, CI/CD, and deliberate architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic grow.
