I build software and hardware.

Currently working on Fiftra, with Rulix on pause. Computational data
science at Michigan State. Whether a given week is code, circuits, or
product depends on what I am trying to build.

The starting condition is usually the same. The thing does not exist, or
it does and I will not pay for it.
