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

Post-launch, scale and dependability take precedence: performance targets, caching strategies, robust authentication, and clean API definitions. With effective monitoring, CI/CD, and well-planned architecture, groups can iterate more quickly while preserving codebase stability as features and traffic expand.
