Building a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on main paths, intuitive navigation, and stable UI elements, enabling rapid delivery without becoming a fragile collection of bespoke screens.

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