About Marie

Administrative assistant & Sales Administration with 3 years of experience in order management, invoicing, payment tracking, follow-ups, customer database updates, and multilingual customer support.

I worked on a work-study basis within an industrial trading company, which taught me to manage the entire Sales Administration cycle: order entry, logistics monitoring, invoicing, Excel reporting, and customer relations.

I am proficient in email processing, inter-departmental coordination (logistics, accounting, sales), digital archiving, and office tools (Excel, Word, Outlook, EBP, Power BI).

I speak French (C2), English (B2), Ukrainian, and Russian (C2), which allows me to provide international customer support.

➡️ I help you save time, streamline your administrative management, and improve your customer satisfaction.
