Giving my all to grow and enjoy work
I have back-office experience in the apparel, IT, equipment manufacturing, and consulting industries. Most recently, I worked in HR for a cosmetics brand, handling recruitment.

Senior Consultant

Having a limited number of words to describe myself I choose...that is one of the keywords, among decide, like, wonder. There are many others. Working with people, I value being aware – of a person, a group, and also of words being used. I think of them as a code passing through our minds – all that is within the light of consciousness shapes our experiences and reactions towards the world. So, what do you choose?
