Building a web application begins with outlining user roles, key scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can launch fast without becoming a fragile collection of bespoke screens.

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