Building a web application starts by outlining user roles, key use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of bespoke screens.

Post-launch, the priorities shift to scalability and dependability: performance budgets, caching strategies, secure login, and clean API definitions. With effective observability, CI/CD practices, and thoughtful architecture, teams can iterate more swiftly while keeping the codebase stable as features and traffic expand.
