Web application development begins with outlining user roles, essential scenarios, and the data model. A solid MVP concentrates on core flows, intuitive navigation, and consistent UI components, so the product can be released quickly without becoming a fragile collection of one-off screens.

Post-launch, scalability and reliability are paramount: performance budgets, caching, secure login, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic increase.
