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

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, secure sign-in, and clean API contracts. With effective monitoring, CI/CD processes, and a well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
