I'm an expert in GNU/Linux systems and other UNIX flavors. I have experience in CDN deployment, Cloud Computing, High Availability, Monitoring and Video Transcoding and Streaming. I've been working with GNU/Linux since I was 14, what makes more than 10 years of experience so I have a good background in its evolution, tools and administration. I also use to implement tools in shell script and python and I use to code my applications in python. In the last 6 years I've been working as systems administrator and Integrator for an IPTV company that offers streaming and web services. I directed projects regarding software distribution and upgrades automatization, product deployment architecture design and products monitorization. I co-designed and co-deployed the cloud computing platform for the company, its CDN with High Availability, its telephony system and other projects. I really like to learn new technologies, test its capabilities and see what can they do. I like to meet new people, work with them and share knowledge and opinions.

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.

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. - Extensive knowledge of sybase db, HA, bigdata. - 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.
