Building a web app begins by outlining user roles, primary use cases, and the data schema. A robust MVP concentrates on essential pathways, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a fragile collection of ad-hoc screens.

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