    United Kingdom - Last active: 28 days ago - Tests: 5

    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 :)
