Building a web app begins by outlining user roles, crucial use cases, and the data structure. A robust MVP concentrates on essential paths, intuitive navigation, and reliable UI elements, allowing the product to be delivered rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching, secure sign-in, and tidy API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate quicker while maintaining codebase stability as features and user demand expand.
