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

Post-launch, scalability and dependability are paramount: performance budgets, caching, robust authentication, and tidy API contracts. With appropriate monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while maintaining code stability as features and traffic expand.
