I am looking for an adjective to describe someone skilled at taking raw materials and combining them and turning them into something beneficial. Relevant professions here include a cook/chef, a materials engineer, pharmaceutical scientist, perhaps even an explosives/demolition expert if they have to combine certain materials.
Originally I was thinking something like "crafty" but I feel that word also has other negative connotations.
Example: Give Joe any material or substance and he can create something great, he's so ________.
