Building a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on primary workflows, straightforward navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad hoc screens.

Post-launch, the main concerns are scalability and dependability: performance budgets, caching, robust authentication, and clean API agreements. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic increase.
