Constructing a web application begins by outlining user roles, essential use cases, and the data schema. A robust MVP emphasizes core workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad hoc screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, secure login, and clean API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining code stability as features and traffic increase.
