Professionally, I'm working on extending Nx, the Elixir ML framework which I help maintain, for distributed and sharded computing. Should have an working v0 by December!
GitHub for the project: https://github.com/elixir-nx/nx
As a side-project, I've been diving back into hardware. Fixed/modded a crappy guitar amplifier I had into a great amp, and the next project in line will be a new version of a digital synth I designed a fey years back
