Santiago Bruni

I have made experience in different technology roles, starting from the users help desk, moving 
through different infrastructure assignments and finally managing an entire Infrastructure team in 
Citi, taking sub-region responsibilities for 3 countries in South America.
I’m constantly looking for new challenges and learning about new technologies. Accountable for my 
work, with good team management and collaborative. Everytime looking to help other teams and to 
give the best client experience.

I consider me a high performance employee, and it is reflected in my performance ratings during my 
career in Citi (with Highly and Exceptional ratings in all the pillars), during my 18 years as Citi employee
