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

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching, safe authentication, and tidy API agreements. Through effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and user demand expand.
