Building a web app begins by outlining user roles, principal scenarios, and the data structure. A strong MVP concentrates on essential pathways, intuitive navigation, and reliable UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take center stage: performance budgets, caching, robust authentication, and clear API agreements. With adequate monitoring, CI/CD, and well-considered architecture, teams can iterate swiftly while preserving codebase stability as features and traffic expand.
