    Student

    Croatia - Last active: 4 months ago - Tests: 6

    I'm interested in new technologies, computer networks, computer security, operating systems and project management. For the last year I have been working with Microsoft and Oracle databases. Beside their procedural languages I learned how to use XQuery and XPath for querying XML documents in both databases. I have experience with BIND DNS and ISC DHCP and network administration, computer security and with Unix/Linux/Window operating systems.. Before accepting any job I will do a detail interview because that's the best way to find out if I can do a job. I guarantee for my work, before any payment I like to show what I did and answer any question you ask me. If my client isn't satisfied with with my work than I won't ask for any money but I will ask where I did wrong. My moto: satisfied client = happy client

    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 server 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. Unix only, Linux preferred. I am a developer of cloud monitoring & management tool M-Script ( http://m-script.org ), a simpler and easier to learn tool compared to alternatives, yet powerful and allowing faster cloud-based deployments including cross-cloud deployments, private clouds support, images management, cloud scripting of maintenance routines and any complex cloud automation (auto-scalability or any event/action programming). No matter how complex (or simple) your setup is, it can save you a lot of time and money and provide a seamless transition from initial proof-of-concept setup to full production infrastructure.
