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

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