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

Post-release, scalability and dependability take priority: performance budgets, caching strategies, secure login, and clean API contracts. With solid monitoring, CI/CD, and a well-thought-out architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
