Building a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential workflows, intuitive navigation, and consistent UI elements, allowing the product to release rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clean API interfaces. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and user demand expand.
