Web application development begins by outlining user roles, key use cases, and the data schema. A strong MVP concentrates on essential flows, clear navigation, and consistent UI components, so the product can be delivered quickly without becoming a fragile collection of ad-hoc screens.

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