Strategy & Operations · AI-Native Builder

Joshua Zimdars

Business Systems Specialist & EA to the CEO/CFO · Golden Limousine International · Ann Arbor, MI

I turn ambiguous business problems into shipped systems. Over 18 months I rebuilt a 35-year-old company's entire S&O stack — pricing, sales ops, dispatch, customer experience, and executive reporting — self-taught, using AI as my primary building tool.
