Building a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without ending up with a fragile collection of ad-hoc screens.

Post-launch, growth and dependability take priority: performance budgets, caching, robust authentication, and tidy API contracts. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
