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

Post-launch, the main priorities are scalability and reliability: performance budgets, caching strategies, robust authentication, and clean API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving the codebase's stability as features and demand grow.
