Stephen Mack

Solutions Engineer, Cloudflare

I build production applications on Cloudflare's edge platform — security, AI, and developer tools.

Every project ships to Workers, runs in 300+ cities, and demonstrates platform capabilities I use with startup customers every day.

About

I'm a Solutions Engineer at Cloudflare focused on AI infrastructure for startup technology companies. My work involves helping engineering teams understand and deploy Cloudflare's platform — from Workers and D1 to AI Gateway and Zero Trust.

I enjoy building with AI agents and diving into the new paradigm — exploring how agents, RAG, and memory systems can be composed into useful products. Each project is an exploration of how these patterns fit together at scale.
