Creating a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on the main flows, intuitive navigation, and consistent UI elements, enabling fast delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, growth and dependability are top priorities: performance budgets, caching strategies, robust authentication, and clear API agreements. With effective monitoring, continuous integration/delivery, and well-considered architecture, teams can iterate quickly while maintaining code stability as features and user load expand.
