Linux sysadmin, cloud deployments specialist

Czech Republic - Last active: 1 day ago - Tests: 9 - Portfolio: 1

I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.

Writer, Editor, Voice Talent

United States - Last active: 1 month ago - Tests: 1

During the last two decades, I have written or edited for top global companies such as Lockheed Martin, Philips Consumer Electronics, and Siemens Medical Solutions. I have also performed video script writing and voice-over for international power equipment company Husqvarna. For one contractor I had outside of ODesk, I traveled to interview or talked on the phone with subjects for profile articles and received some very favorable response from the subjects and the employer about the articles I produced. The contract, which lasted nearly two years, was a very fruitful association. I am an excellent editor and derive satisfaction from helping people sharpen their content. A challenge of editing is its subjective nature--all sorts of styles exist within the parameters of commonly accepted grammar guidelines. So, every editing job involves give and take between writer and editor, as well as a "meeting of the minds" in terms word usage, phrasing, and style. I enjoy working with authors to craft content that is clear and interesting and accomplishes their goals. I really appreciate ODesk because of its professionalism and the opportunity it offers to work with people involved in interesting projects all over the world.
