Building a web application begins by outlining user roles, main use cases, and the data schema. A robust MVP concentrates on essential pathways, intuitive navigation, and consistent UI elements, enabling the product to launch rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, safe authentication, and well-defined API contracts. With solid monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and user load expand.
