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 fast delivery without becoming a brittle collection of ad-hoc pages.

Post-launch, growth and dependability are top priorities: performance budgets, caching, secure login, and clean API interfaces. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving code stability as features and traffic increase.
