About Me

I graduated in Communication Networks Engineering from the University of Brasília, Brazil. During the Fall 2015 and Spring 2016 I attended Colorado State University, USA and during the Summer 2016 worked as a TA for the CS430 - Database Systems class.
My first job with Systems Administration was in 2012, when I was admitted to the University of Brasilia, although my experiences fiddling with computers and networks started around 2005.
When I was 11, I learned Delphi 7 and began to play with programming. Many years passed, I learned a few more programming languages and left aside programming to focus on System Administration and Networks skills.
