Creating a web application begins with outlining user roles, essential use cases, and the data structure. A robust MVP concentrates on main user journeys, straightforward navigation, and consistent UI elements, enabling rapid delivery without evolving into a fragile collection of ad-hoc pages.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, strong authentication, and clean API contracts. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
