-- Red Hat Certified -- Beginning with Ubuntu in 2008, I now manage CentOS servers for LogicDudes.com, my local tech support company. I have a wide range of experience including setting up headless KVM virtual hosts, configuring Nginx and Apache with Mod Pagespeed, encrypting filesystems and network traffic, monitoring system performance with Nagios, troubleshooting selinux complications, and automating common tasks with scripts. I am certified by Red Hat and stay up to date with the latest methods and services. I do my best to make sure all of my systems run at their best and are as secure as possible. My favorite thing about Linux is that anything is possible and everything is free, somebody has probably done it before and documented everything. -- Script Writer -- At the end of the day, everything is about text manipulation. I write scripts in bash, php and perl to automate tasks and work with websites. Everything from scapers to emailers to automated submitters, I can create custom scripts to automate any process. My scripts are great because they are created to do one process and to do it well. They are also properly documented so future updates are quick and easy.
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 worked for many years in the managed services and server hosting industries, and have worn many hats. Everything from basic website management to troubleshooting large scale multihomed websites with clustered MySQL database backends. Currently I am handling Linux administrative and devops development work in both chef and puppet, in both Rackspace and AWS cloud provider spaces. What am I experienced with? The list is long: * Linux RHEL/CentOS, Gentoo, Debian/Ubuntu? You name it I've used it. * Configuration Management / devops I am currently and have previously supported customers with large deployments via chef and puppet. This is the kind of work I enjoy doing, so if you need someone who can handle a puppet manifest or chef cookbook I'm the guy to talk to. * Enterprise Networking. I have not only supported customers with their networking needs, but I maintain an extensive home lab for tinkering and testing. This includes a Cisco ASA 5505 and Catalyst 2960 switch. * Virtualization. Xen, VMWare, KVM, AWS, you name it I've worked with it. I'm currently looking to expand that experience a full fledged openstack deployment. * Storage. Whether it is something relatively mundane like NFS, or something complex like Ceph or your SAN/NAS' iSCSI or fiberchannel HBA. * Cloud hosting I am currently supporting clients in Amazon, Rackspace, and Digital Ocean. Further, I used to work for Rackspace so I have experience on both sides of the asile with their products. In summary I have been doing this long enough with enough different products and companies that I can meet any challenge put forth to me. With your assistance, my presonal github repository will gain something new and interesting. Personal blog: http://jowrjowr.github.io/
