Building a web application begins by defining user roles, core scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and dependable UI components, allowing the product to launch rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure authentication, and clean API contracts. With solid monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic rise.
