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

Post-launch, scalability and dependability take center stage: performance envelopes, caching strategies, robust authentication, and clear API interfaces. By implementing solid monitoring, CI/CD pipelines, and well-considered architecture, teams can iterate more quickly while preserving code quality as features and traffic expand.
