Building a web app begins by outlining user roles, primary use cases, and the data schema. A robust MVP concentrates on essential flows, intuitive navigation, and reliable UI elements, enabling rapid delivery without becoming a brittle collection of standalone screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, secure login, and clear API interfaces. Through effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
