Building a web app begins by outlining user roles, essential scenarios, and the data schema. A strong MVP emphasizes fundamental flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc pages.

Post-launch, scalability and dependability take the lead: performance budgets, caching, robust authentication, and clear API contracts. With adequate monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
