Building a web application begins by outlining user roles, primary scenarios, and the data structure. A solid MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling the product to launch swiftly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, secure authentication, and clean API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more rapidly while maintaining codebase stability as features and load expand.
