Building a web application begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential flows, intuitive navigation, and reliable UI elements, allowing the product to launch swiftly rather than becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clean API interfaces. Through effective monitoring, CI/CD, and well-planned architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic expand.
