👋 Hi. I’m Ran.
I build software for people who build software.
I created yfinance and other widely used open-source software (50 million downloads per month),
wrote two books on Agentic AI,
host the Old School / New Tech podcast,
and currently building MUXI and
Cloop — infrastructure for the next generation of software teams.
I offer CTO-as-a-Service at Automaze
and building Resident AI at VarOps.
