35+ years of production code. Still shipping.
I created 📈 yfinance and other open-source tools used by millions of developers – totaling ~50M downloads per month w/ 50K+ GitHub stars. I wrote 📚 two books on production AI, host the 🎙️ Old School / New Tech podcast, and write 💌 a newsletter for developers, indie makers, and entrepreneurs.
I'm building MUXI (open-source infrastructure for AI agents), and running managed software factories at Automaze Works, and Resident AI at VarOps.
