Crafting a web application begins by outlining user roles, primary use cases, and the data model. A strong MVP prioritizes essential flows, intuitive navigation, and consistent UI elements, so the product can launch fast without turning into a brittle collection of ad-hoc screens.

Post-launch, performance, reliability, and scalability take center stage: budgets for performance, caching strategies, secure user authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
