I graduated in business administration and during this period I had the opportunity to do an internship at Citibank, where I got know the credit card fraud area. After some time, one of my biggest dreams was to live abroad and experience a new culture, totally different from mine. I went to live in Ireland and had the great pleasure of studying and working there, as well as meeting wonderful people. After three years I returned to Brazil and went back to the same company I was with, Citibank and in the same area.After a little more than one year, they informed me about the sale of the bank in Brazil and Itaú Unibanco made the purchase and we were migrated to the new bank where I am currently. Today I work in the chargeback for credit card. I am responsible for all transaction with any divergence, without authorization, different amount between authorization with base II or clearing, late presentment, chargeback rejected in Visa and Mastercard . These are some of the activities I work at.
