About

I have over 20 years of experience working in software development and UNIX like systems. Currently, I work as a DevOPS Engineer with a great team at Sao Paulo State University (Unesp). We work in close partnership with Caltech and the Large Hadron Collider (LHC), the world's largest and most powerful particle collider, and is the most complex experimental facility ever built, and the largest single machine in the world. The LHC remains the latest addition to CERN’s accelerator complex. During my Master's degree studies at USP I worked on a Pseudo File System inside Linux Kernel for network packets debugging. With this tool the system administrator it would be able to sniffer network packets and statistics without using libpcap or any user space tool other than cat, grep and tail. Currently I'm more involved with the Software Defined Network (SDN) team, building software stack for high speed data transfers (~ 1 Tbps). I am also a 'luthieria' art apprentice. Competencies: development, managment, devops, ansible, python, c, network, sdn, openflow, api, tcp/ip, debian, linux, git
