What I do
I run logistics at IVB Media Services, and I built the software it runs on.
Inventory, orders, purchasing, QuickBooks and sales all live in one platform I designed, deployed and keep running. Outside work I build automated research for prediction markets, and I'm working through an MS in Data Science at CU Boulder.
The systems below run every day. None of them is a class project.

Saw you're hiring a post production manager. When a show wraps, we rent LTO-8 and LTO-9 decks by the week so the archive doesn't need a deck purchase.

How I work
I studied marketing at the University of Idaho, and before that I wrote about college football. I didn't start out as an engineer, and I still begin every project with the person who has to use it.
At IVB I started by running shipping and receiving. What I needed to know lived in QuickBooks, spreadsheets and email, so I built one place for it. Then I kept going, one real problem at a time: receiving by serial number, signatures at the counter, prices from every distributor.
I trust tests over hunches. In my trading research most ideas fail on data they have never seen. I count that as a result, because it is money that never went into a bad idea.
The master's degree is the foundation under the work I already do every day: statistics, machine learning and data engineering, learned properly.
