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

Post-launch, scalability and reliability take priority: performance budgets, caching strategies, secure login, and clean API contracts. With effective monitoring, CI/CD pipelines, and well-considered architecture, teams can iterate more quickly while preserving code stability as features and traffic expand.
