Cashier, pharmacist

Hello. My name is Denis, I am 27 years old. I am from Russia. I have worked in a veterinary clinic since I was 17 in the following positions (veterinarian, pharmacist, sometimes took shifts as an administrator/receptionist). My English is at level B1 and I am trying to improve it. I am well versed in medical products. I am looking for a job as a cashier or pharmacist (in a supermarket or drugstore), possibly as a salesperson in a pet store. I am looking for a cash job, as the documents are still in process.
