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

Post-launch, scalability and dependability take precedence: performance targets, caching strategies, robust authentication, and clean API agreements. With proper observability, CI/CD pipelines, and deliberate architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic expand.
