Building a web application begins by outlining user roles, primary use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, secure login, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while preserving codebase stability as features and traffic expand.
