Building a web app begins by outlining user roles, primary use cases, and the data structure. A robust MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling a fast release without becoming a fragile collection of bespoke screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, secure authentication, and tidy API contracts. With appropriate monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features expand and traffic increases.
