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

Post-launch, scalability and reliability take the lead: performance budgets, caching, secure login, and clean API contracts. With solid monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
