Ugo Bellavance, who has done most of his studies in e-commerce, started using Linux at Red Hat 5.2, got Linux training from Savoir-Faire-Linux at age 20, and got his RHCE on RHEL 6 in 2011. He's been a consultant in the past, but he's now an employee for a provincial government agency for which he manages the infrastructure (servers, workstations, network, security, virtualization, SAN/NAS, PBX). He's a big fan of open source software and its underlying philosophy. He's worked with Debian, Ubuntu, SUSE, but what he knows best is RHEL-based distributions. He's known for his contributions to the MailScanner project (he has been a technical reviewer for the MailScanner book), but also dedicated his time to different open source projects such as Mondo Rescue, OTRS, SpamAssassin, pfSense, and a few others.
