    First thing off: I don't use skype nor ICQ (as they are proprietary closed protocols), but I have jabber. 20 years of experience with almost every flavour of industrial unixen, portable programming (C-99, POSIX, autotools), portable shell programming (POSIX.2) — dealt with many subtleties in different implementations. I'm honest, trustful and reliable. Tenacious, can solve any problem if it's solvable. If I apply, that means that I'm 100% sure I can do the job meeting my quality standards. I don't tolerate obscure corners of the implementation, I understand how it works to the last detail, that implies doing no cruft. The code must “just work”, elegant and concise. There's too much non-working, ugly and bloated stuff around:( Lifetime warranty for my work (doesn't include new features though). • Automating everything • UNIX system programming including embedded systems • Web scraping and any other text transformations/extractions. • Consulting about UNIX shell scripting (bourne shell, bash, awk, sed, [BE]RE etc). • Anyway, the list is not full, as I have experience ranging from Jenkins CI setups and maintenance to writing parsers with lex/yacc. From IP traffic handling in C++ (libnetfilter_queue plus iptables custom kernel module) to product installers. I use Gentoo and EMACS. PS. oDesk thinks my photo isn't “professional”. Therefore I have none. I'm easily googlable though, and if you want you can find any information about me outside of oDesk.  less

    Hi, my name is Anton Yushkov. In my portfolio, there are a few scripts that I developed. But I don't know how I can show my sysadmin jobs, not all of them have a frontend. I believe my strong points are my Knowledges, Educability (there are a lot of tools in the world that I didn't know previous), and Punctuality. My #1 goal is always be to meet your needs at deadline. When I start new project, I like to speak with the client to take a whole and clear understanding of his/her needs and vision of projects. So I can choose the best way to reach the client's needs. I strive to help more fully and accurately. Since 2008, I've been a system administrator of windows and linux systems. It is servers for office local networks and internet sites and services. Also in 2011, I got RHCSA certificate, so since 2011 I've been specializing in linux systems. System administration - is the complex way, so I can do a lot of various jobs, but I prefer setup servers, configure automating self-support (backups, checks, other) and write scripts (bash, python). Please take a look at my work history for comments from other clients. Thank you in advance for your time and consideration. I look forward to work with you soon. I have a degree Engineer of Automation, Remote Control and Communication from University of Railways. Listed below are my experience and skills: - Web servers: apache, nginx, proxy-sites (apache and nginx), ssl. - DB: installation and setup of postgresq and mysql. Also mongodb and sybase. - Security Linux servers: iptables/ufw, openvpn, fail2ban and other. - Backup: duply (duplicity), bacula, bash scripts. - Monitoring: zabbix, cacti, xymon (hobbit). - Virtual servers: ESXi, VBox, Hyper-V, KVM. - Management server: CFEngine, ansible, - Mail: exim, dovecot, roundcube. - VOIP: Asterisk - Elastix. - Program languages: python, bash, php, perl, bat and other if need. My greate job is local network of developer company: ESXi servers with vm's and one NAS for backups. Services: Subversion (legacy) Gitlab Nexus Sonatype YouTrack TeamCity OpenGrok (search of code) Crucible (code review) gateway with proxy-site for all services and Active Directory authorization. mail (exim+dovecot+roundcube+postfixadmin) some self-writed services (autogenerate openvpn keys, signes for e-mails) time sheet service and others.
