Web application development begins with identifying user roles, key scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and predictable UI components, so the product can ship rapidly without becoming a fragile collection of one-off screens.

After release, scalability and reliability are the top priorities: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while maintaining a stable codebase as features and traffic expand.
