Web application development begins by outlining user roles, key scenarios, and the data model. A strong MVP emphasizes core flows, straightforward navigation, and predictable UI components, enabling the product to ship rapidly without becoming a fragile collection of one-off screens.

Post-launch, scalability and reliability are the top priorities: performance budgets, caching, 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.
