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

Following launch, scalability and dependability take precedence: budgeted performance, caching strategies, secure login, and clean API agreements. With proper observability, CI/CD pipelines, and thoughtful architecture, teams can iterate more rapidly while preserving code quality as features and traffic expand.
