Building a web app begins by outlining user roles, primary use cases, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling fast delivery without evolving into a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clear API contracts. With adequate monitoring, continuous integration/continuous deployment, and well-considered architecture, teams can iterate rapidly while maintaining codebase stability as features and traffic increase.
