Web application development begins by outlining user roles, essential use cases, and the data model. A strong MVP concentrates on the core flows, intuitive navigation, and consistent UI elements, allowing the product to ship quickly without becoming a brittle collection of one-off screens.

Post-launch, scalability and reliability become paramount: setting performance budgets, implementing caching, enforcing secure authentication, and maintaining clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
