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

Post-launch, prioritizing scalability and reliability is key: performance limits, caching, strong authentication, and clean API agreements. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
