Self-taught programmer. 35+ years of production code. Still shipping.
I created 📈 yfinance and other open-source tools used by millions of developers — 30M+ downloads per month w/ 50K+ GitHub stars. I wrote 📚 Production-Grade Agentic AI, the handbook for autonomous systems that actually hold up in production.
These days I'm building 🧠 MUXI (open-source infrastructure for AI agents) and Cloop (autonomous engineering control plane), and running 🏢 Automaze (CTO-as-a-Service, 92% retention) and VarOps (systems-level advisory for companies building with AI).
I host 🎙️ Old School; New Tech and write 💌 Code Daddy — a newsletter for developers, indie makers, and solo entrepreneurs.
