I maintain accurate e-commerce listings, verify product data, and support reliable digital commerce operations.
What I'm looking for
I create and maintain accurate book listings for a family business on Mercado Libre, organizing product information, researching details, and setting appropriate prices for individual items.
I review listings before publication or modification, respond clearly and promptly to customers, and independently support day-to-day digital commerce operations while managing multiple tasks.
Through social service, I recorded and organized student attendance and participation information in Microsoft Excel, maintained structured academic records, and supported case-discussion sessions.
My background in Pharmaceutical Chemistry and coursework in pharmaceutical legislation, food innocuity, and quality control reinforce my focus on accuracy, information verification, and following established processes.
