AI engineer · Revenue operator · Founder

I build the AI — and I can prove it moves revenue.

Most AI engineers can't sell. Most salespeople can't build. I've shipped 78 production MCP servers and 132 published packages, designed and built live client products, and personally closed $50M+ in sales. One person, both halves.
