Building a web application begins by outlining user roles, principal scenarios, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

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