Building a web application begins by outlining user roles, main use cases, and the data structure. An effective MVP concentrates on essential flows, intuitive navigation, and reliable UI elements, enabling a speedy release without becoming a brittle collection of scattered screens.

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, robust authentication, and clear API contracts. With solid monitoring, CI/CD, and well-planned architecture, teams can move faster while maintaining codebase stability as features and traffic increase.
