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 delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching strategies, secure authentication, and well-defined API contracts. With effective monitoring, CI/CD, and a well-considered architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
