Another good word
Bricoleur: A person who engages in bricolage; a person who creates things from existing materials, is creative and resourceful: a person who collects information and things and then puts them together in a way that they were not originally designed to do - from the French-language verb bricoler, meaning "to tinker" or "to fiddle" - the French language's equivalent of the English phrase "do-it-yourself".
Bricolage is also often contrasted with engineering: building by trial and error rather than based on theory.
