Building a web app begins by outlining user roles, primary use cases, and the data schema. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, strong authentication, and tidy API contracts. With effective monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving code stability as new features and traffic expand.
