Building a web app begins by outlining user roles, main use cases, and the data schema. An effective MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a fragile collection of ad-hoc screens.

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