Who is "Fredo", did he/ they ever give interview

I have a small but growing collection of (purchased) Fredo plugins. With Fredo being one of the beacons in the SU plugin world, I can't help wondering: Who is Fredo ? A one-person-show ? A company ? I can't find anything about him/ them / ...

But I would love to know the story behind, all the complex math that must be behind the plugins, how it's done, if LibFredo could potentially be a product for other plugin devs etc etc. So many questions.
