Creating a web application starts by outlining user roles, key use cases, and the data structure. A strong MVP concentrates on essential flows, intuitive navigation, and stable UI components, so the product can ship rapidly without becoming a brittle collection of custom screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, secure login, and clean API contracts. With proper monitoring, CI/CD, and careful architecture, teams can iterate more quickly while keeping the codebase robust as features and traffic grow.
