The Vercel Agency Deployer

A developer at a web agency or a freelancer who deploys and manages 20–100 client projects on Vercel. They chose Vercel because the developer experience is excellent and Next.js deploys are zero-config. But managing 50 projects across 15 clients has turned deployment into project management. They spend as much time in the Vercel dashboard organizing teams and domains as they do writing code. They know every deployment preview URL is a demo link, and they've sent the wrong preview to the wrong client exactly once.
