Building a web application begins by outlining user roles, essential use cases, and the data structure. A robust MVP concentrates on fundamental flows, intuitive navigation, and consistent UI elements, enabling the product to launch rapidly without becoming a fragile collection of ad hoc screens.

Post-launch, the priority is scalability and dependability: setting performance ceilings, caching strategies, secure sign-in, and tidy API agreements. With effective monitoring, continuous integration/delivery, and careful system design, teams can iterate more quickly while preserving code stability as features and user demand expand.
