Kicking off web app development involves outlining user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, so the product ships swiftly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability take precedence: performance budgets, caching, secure 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 expand.
