Building a web application begins by outlining user roles, principal use cases, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Once deployed, scalability and reliability take center stage: performance budgets, caching strategies, secure login, and clean API contracts. With proper monitoring, CI/CD pipelines, and a thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic expand.
