I'm looking for a word to describe someone who builds new inventions from technological scraps. I'm a writer, and it's for a cocky post-apocalyptic pirate who steals/raids and looks for bits and pieces of old technology and then builds completely new devices from them.
Words like tinkerer, scavenger, inventor, and raider were close, but not quite right because the there's a level of skill that tinkerer doesn't imply, an aspect of going off of past inventions and transforming them that inventor doesn't include, a fierceness that scavenger lacks, and a mechanical/technological knowledge raider doesn't have.
I feel like this word exists but I just can't remember it. It is also going to be the running name of this pirate if I can find the word.
