Building a web application begins by outlining user roles, main scenarios, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling a release that avoids a fragile collection of ad hoc screens.

Post-launch, the focus shifts to scalability and reliability: performance budgets, caching strategies, robust authentication, and clean API boundaries. With effective monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
