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

Post-launch, scalability and reliability take the lead: performance budgets, caching, robust authentication, and well-defined API contracts. Through effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
