About Me

I hold a Communication Networks Engineer title from the University of Brasília, Brazil.
My interest for computers started around 2005, when I was 11 years old, with the first big step being learning Dephi 7. When I started my university studies in 2012, I secured a job as a System Administrator and during that time built a broad skillset around Linux and Automation.
After moving to Germany, I obtained my own ASN and started learning Networks diligently.
My current interest is in routing (especially BGP) and subscriber management using the VPP data plane.
