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

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure login, and clear API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and user load expand.
