Creating a web application begins with outlining user roles, main scenarios, and the data structure. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without morphing into a fragile collection of ad-hoc screens.

Post-launch, the priorities shift to scalability and reliability: budgeted performance, caching, secure sign-in, and clean API interfaces. With proper observability, automated pipelines, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
