Building a web application begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on essential paths, 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 are paramount: performance budgets, caching strategies, secure login, and clean API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate rapidly while maintaining code stability as features and user load expand.
