Creating a web application begins with identifying user roles, essential use cases, and the data model. A robust MVP concentrates on core workflows, clear navigation, and dependable UI components, so the product can ship quickly without becoming a fragile collection of one-off screens.

Post-launch, scale and reliability take center stage: performance budgets, caching strategies, secure authentication, and clean API contracts. With solid monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
