Developer · Infrastructure engineer · Founder, Halfservers LLC

I started with a screwdriver and a broken computer.

I'm Jeremiah Kroesche, a developer and infrastructure engineer from Nebraska. I kept working my way up the stack: hardware, Linux, networking, then full web applications.

Somewhere along the way I founded Halfservers LLC to do infrastructure design and management for people who need someone comfortable thinking across every layer, from the silicon to the CSS.
