Building a web application begins by outlining user roles, core scenarios, and the data model. A strong MVP concentrates on essential workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of individual screens.

Post-launch, scalability and reliability take the front seat: performance budgets, caching, secure authentication, and tidy API contracts. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
