Kadeem Assistant Merchandiser

Merchandising is all about getting the right stock, in the right place, in the right quantities, to drive up profit. So I like getting out to stores, seeing the products on display and hearing what customers are saying. That helps me to seize the moment and capitalise on current opportunities to go way beyond forecast.

I am fascinated by fashion trends but for me it really makes sense when I see the sales figures on screen. When I’m able to paint the picture with percentages, we can be more innovative as a team.
