Web app development begins by outlining user roles, key use cases, and the underlying data model. An effective MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling the product to release quickly without becoming a brittle collection of ad-hoc screens.

Following launch, performance, scalability, and reliability take center stage: performance budgets, caching, secure authentication, and clean API contracts. With proper observability, CI/CD, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic increase.
