    Rather than reading my resume you perhaps want to check my "stackoverflow" profile just to taste what questions I've asked and which ones I've answered ;) http://goo.gl/5yWJat 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 :)

    Linux/Unix engineer

    Russia - Last active: 11/28/2014 - Tests: 5

    I am a Linux/Unix engineer. I have a good Network and flexible tuning Firewall skills on Linux. Already more 11 years have been working with Gentoo Linux. About 3 years have been performing different tasks on Unix systems like AIX, HP-UX and SunOS. Almost 45% of time I have managed virtual disks on Storages through the SAN including creating disk and zoning up to extending Unix file systems online. About 30% of time takes virtualisation and deployment infrastructure. Other time takes scripting with Bash, Perl, administration of Oracle or may be MySQL databases. Of course troubleshooting is best theme for me, but i don't have so much time to spend it.
