Creating a web app begins with identifying user roles, primary scenarios, and the data schema. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of bespoke screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clean API contracts. With good monitoring, CI/CD, and well-considered architecture, teams can iterate rapidly while maintaining code stability as features and traffic expand.
