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

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure authentication, and clean API agreements. Through solid monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
