To be honest you might get away with moving the term chemistry forward a couple of decades
Beginning around 1720, a rigid distinction began to be drawn for the first time between “alchemy” and “chemistry”.[104][105] By the 1740s,“alchemy” was now restricted to the realm of gold making, leading to the popular belief that alchemists were charlatans, and the tradition itself nothing more than a fraud.[102][105]
I’m a chemist, so I’d just tell them that I’m an alchemist.
Ooh, good idea. I’m an alprogrammer. Or is it alware algineer?

So close, yet so very wrong.
Apothecary might be better.
