Building a web application begins by outlining user roles, essential use cases, and the data structure. A robust MVP concentrates on primary workflows, intuitive navigation, and stable UI elements, enabling rapid delivery without becoming a fragile collection of scattered screens.

Post-launch, the emphasis shifts to scalability and dependability: performance budgets, caching strategies, strong authentication, and clear API contracts. With effective monitoring, continuous integration/delivery, and careful architecture, teams can iterate quickly while maintaining codebase stability as features and user demand expand.
