Building a web application begins by outlining user roles, essential use cases, and the data schema. A strong MVP emphasizes core pathways, intuitive navigation, and consistent UI building blocks, enabling rapid delivery without evolving into a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability become paramount: performance budgets, caching strategies, secure login, and clean API agreements. With solid monitoring, CI/CD practices, and deliberate architecture, teams can evolve faster while preserving codebase stability as features and traffic expand.
