Building a web app begins by outlining user roles, main use cases, and the data schema. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to ship rapidly without becoming a brittle collection of bespoke screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure login, and clean API designs. With appropriate monitoring, CI/CD, and well-considered architecture, squads can iterate quicker while preserving code stability as features and traffic increase.
