    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. All of it have a backup local and offsite with automate scripts and howto's for restore in case a fire in the office J  less

    I'm a senior developer and sysadmin exclusively focused on Linux/Unix environments. My experience as a developer range from building scripts for sysadmin tasks up to full mvc web applications. I have been mainly developing backend software for last decade. As a SysAdmin I only work on Linux or Unix platforms, and my experience involves all the aspects of systems administration. I'm really interested in building strong and long term business relationships with clients, so long term projects are welcome. However since i'm new as a freelancer, I would gladly work on short terms projects as well.  less

    My main skills are C, C++, Matlab, Python, Simulink, GPGPU (CUDA, OpenCL), machine learning, computer vision (incl. OpenCV), DSP (audio processing, image processing). I work with these technologies for several years and can show projects in which I used them. My additional skills are are: Javascript, Angularjs, Ruby, Haskell, C#, SQL, Qt... I used these technologies to solve minor tasks, not large projects as for the "main skills". Batteries included: unix shell scripting, vcs (hg, git), ssh, makefiles. The projects I most proud of: * Development of the "high-level" algorithmic parts of a satellite sun tracker. A sun tracker is a device that helps a satellite to find its orientation. I was to develop algorithms of searching, catching and tracking sun. Devices that use the algorithms I developed are being set on several types of satellites. * Development of mathematical methods which improve accuracy of different devices including the sun tracker above. For example, my algorithm that compensates effects of temperature increases device accuracy by approx. four times (from 7 to 2 arcminutes). * I also developed algorithms for devices that are not in production yet: rangemeters, anglemeters, 3d scanners etc. and helped with the development of algorithms of statellite Earth tracker. * Research and development of the way to optically find parameters of thin films. It was an optimization problem which I tried to solve using different methods (including genetic algorithms and particle swarm optimization). I found a solution and it was very computationally-heavy, that is why I wrote the core algorithm with CUDA and Thrust. * I developed an interactive mode for Clay programming language (claylabs.com/clay/) that uses LLVM JIT technique. My patches can be found in the work-in-progress branch at github (https://github.com/jckarter/clay/pulls/galchinsky?direction=desc&page=1&sort=created&state=closed). Unfortunately the project is not being developed now. * Odesk clients gave me opportunities to help them in different interesting fields. I made several interesting projects: image stitching, GPGPU financial app., semi-automatic tumor detector and a dozen of small projects that are listed in my odesk profile.  less
