Building a web application begins with outlining user roles, primary use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling the product to ship fast without turning into a fragile collection of ad-hoc screens.

Post-launch, performance and reliability take center stage: budgeted performance, caching, secure login, and clean API boundaries. With diligent monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more quickly while preserving a stable codebase as features and traffic expand.
