Beginning with web app development involves outlining user roles, key use cases, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling the product to ship rapidly without becoming a fragile collection of fragmented screens.

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