I am a Linux Sys Admin with extensive experience in support and installation of Linux servers and data centers for Infoplace. I have more than 7 years of experience in supporting companies in various segments, totaling approximately 200 servers installed. In this role, I was managing two teams, one with three people in Linux support and other with four people in microcomputers support. I was responsible for client relationships and worked directly with the small, medium and large companies support and critical servers. I have much experience with supporting and creating solutions for companies of all sizes, local and remote, with different distributions (CentOS, RedHat, Fedora, Scientific Linux, Ubuntu, Debian), in various environments and types of equipment. Now I'm living in Brazil, but when I have been in Los Angeles for 2 mounths for vacations, I saw a rising up city in my area, so I believe that a remote job would be the best option to start this process, that can soon live and work in los angeles and improve more my skills and contribute to improve for your company too.

Currently I'm employed by the very successful VoIP provider, where my main duties are to look after Linux server farm. Occasionally I create web user interfaces for clients, and I prefer python for such tasks, particularly I like Web2py framework. On my daily workflow there are times when I have to do DBA stuff, that is extracting and parsing various medium sized (~300K rows) data sets. Mostly this is a combination of MySQL and Python-Pandas. I do my best to replace MySQL with Postgresql whenever I can, as I like it more. I'm quite skilled in writing bash scripts, which I use in my system administration tasks on daily basis. Standard linux text manipulation tools are always on my menu - awk, sed, grep. Also I'm quite passionate about networking, network interface configuration, editing routing tables, setting up firewalls, capturing packets and etc. Last but not least, as I work for the VoIP provider I spend enough time in the Asterisk jungle, no more comments in here :)
