Building a web app begins by outlining user roles, essential scenarios, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to launch swiftly without becoming a brittle collection of isolated screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure authentication, and tidy API contracts. With good monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic increase.
