Building a web app begins by outlining user roles, key use cases, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling the product to launch quickly without becoming a brittle collection of ad-hoc screens.

Once deployed, scale and dependability take priority: performance budgets, caching strategies, secure login, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can move faster while keeping the codebase stable as features and traffic expand.
