Web app development begins by outlining user roles, essential use cases, and the data model. A robust MVP concentrates on the main flows, intuitive navigation, and consistent UI elements, enabling a quick release without becoming a fragile collection of bespoke screens.

Post-launch, scalability and reliability become the top priorities: performance budgets, caching strategies, secure authentication, and clean API contracts. With proper monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic grow.
