Hello there,

I am Ruby and Elixir freelance software engineer.

Here you can find some of my open source contributions such as InvoicePrinter, a Ruby library to make PDF invoices.

If you want to support me, the best way might be to buy my new book Deployment from Scratch.

If you are curious to read something from me, go read my blog.

~ Josef
