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

Post-launch, scalability and dependability are paramount: performance budgets, caching, secure login, and clean API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
