Building a web application begins by outlining user roles, key use cases, and the data model. An effective MVP prioritizes essential paths, straightforward navigation, and consistent UI elements, enabling rapid delivery without turning into a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability take the lead: performance budgets, caching strategies, secure user authentication, and clean API contracts. With proper monitoring, CI/CD practices, and a thoughtful architecture, teams can iterate more quickly while preserving code stability as features and traffic grow.
