Creating a web application begins by outlining user roles, key use cases, and the data schema. A strong MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of bespoke screens.

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