Among my activities in 9 years of experience as a Linux/Unix systems administrator, I worked in the development, maintenance, and implementation of support tools for activities such as communications between teams and customers, and prevention/correction of failures in equipment, processes, and systems. Web servers, email, DNS, VoIP, virtualization, and monitoring, with emphasis on the latter, where I became specialized in the implementation of Zabbix. In addition, I also worked on systems integration, starting from middleware I've developed from scratch, mainly with Python programming language.
