Building a web app begins with outlining user roles, main use cases, and the data schema. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are the top priorities: performance budgets, caching strategies, secure login, and tidy API contracts. With solid monitoring, CI/CD pipelines, and careful architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
