Building a web application begins by outlining user roles, essential scenarios, and the data structure. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI components, allowing the product to launch swiftly without becoming a fragile collection of ad-hoc screens.

Post-launch, scale and dependability take precedence: performance budgets, caching, safe authentication, and clean API contracts. With effective monitoring, continuous integration/delivery, and well-planned architecture, teams can iterate more rapidly while preserving code stability as features and traffic expand.
