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

Post-launch, scalability and dependability take the lead: performance budgets, caching strategies, secure sign-in, and clean API agreements. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic increase.
