SOLVED. SciFi Audiobook - programmer pulled into magic world by goddess. Choses "meta magic" as his free skill.

[MR JP TAPSELL]

The engineer/programmer guy becomes a magician, whose magical skill is in magic itself. He uses this to build machines that can make magic items themselves. He builds castles, cars, guns, and so on.

He has sex with pretty much every female character in the book.

Oh, I finally found it myself!
