Web application development begins by outlining user roles, key use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and predictable UI components, so the product can be shipped quickly without becoming a brittle collection of ad-hoc screens.

Following launch, scalability and reliability are paramount: performance budgets, caching, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while preserving a stable codebase as features and traffic expand.
