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 elements, so the product can be shipped rapidly without becoming a fragile collection of haphazard screens.

Post-launch, scalability and reliability are the top priorities: performance budgets, caching, robust authentication, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
