Building a web application begins with outlining user roles, key scenarios, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can ship quickly without becoming a fragile collection of one-off screens.

Post-launch, scalability and reliability take priority: performance budgets, caching strategies, secure authentication, and 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.
