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

Post-launch, scalability and reliability become top priorities: budgeted performance, caching strategies, robust authentication, and clean API interfaces. Through effective monitoring, CI/CD practices, and deliberate architecture, teams can iterate swiftly while preserving a stable codebase as features and traffic expand.
