    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.
