Developing a web application begins by outlining user roles, main use cases, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to launch promptly without becoming a fragile collection of isolated screens.

Post-launch, scalability and reliability take priority: performance budgets, caching, secure authentication, and clear API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate rapidly while maintaining a stable codebase as features and traffic expand.
