Building a web app begins by outlining user roles, essential scenarios, and the data model. A robust MVP emphasizes main workflows, intuitive navigation, and consistent UI elements, enabling speedy delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, strong authentication, and tidy API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate rapidly while maintaining codebase stability as features and traffic expand.
