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.
Projects
Application Security
Zero Trust Demo Lab
Personal Mac enrolled in WARP, SE Intel protected behind a Tunnel and Access, Gateway filtering all outbound traffic, DLP blocking PII exfiltration, and CASB auditing Google Drive and GitHub — eight layers, one dashboard.
Edge Security Lab
Turnstile Ephemeral IDs for mobile WebView fraud detection and a five-signal scoring engine that serves tiered fake data to bots instead of blocking them. Built for a fintech customer call.
AI & Agents
SE Intel
Role-gated multi-agent intelligence platform. Two agents, five roles, three-tier RAG knowledge base, streaming SSE, cross-session memory, and an LLM-as-judge eval harness.
AI Technical Sales Co-Pilot
Describe a prospect's tech stack — get back a Cloudflare migration plan, component mapping, and cost comparison. Grounded in an 80-chunk Vectorize RAG knowledge base.
Developer Platform
FIFA World Cup Draft Pool
Fantasy draft order for 48 users across 5 pools. Monte Carlo scoring model validated against real tournament data — 103 matches, tier balance confirmed within 10-point spread of predictions.
Golf Practice Plan
12-week golf practice tracker with cross-device KV sync. PIN-based authentication, session model, mobile-first UX. Built without a framework in ~1,500 lines of TypeScript.
