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

After deployment, scalability and reliability take precedence: performance budgets, caching, robust authentication, and clear API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
