Building a web application begins by outlining user roles, key use cases, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling quick delivery without turning the product into a fragile collection of bespoke screens.

Post-launch, scalability and reliability become the priorities: performance budgets, caching strategies, secure authentication, and clean API contracts. With robust monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
