Building a web application begins by outlining user roles, primary use cases, and the data structure. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, robust authentication, and clean API contracts. With effective monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
