Building a web application begins with outlining user roles, primary use cases, and the data model. A solid MVP should prioritize essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without turning the product into a fragile collection of ad-hoc screens.

Once launched, scale and reliability become the top concerns: setting performance budgets, implementing caching, securing authentication, and defining clean API contracts. With proper monitoring, CI/CD, and a thoughtful architecture, teams can iterate more quickly while preserving a stable codebase as features and traffic increase.
