    Igor S.

    Linux sysadmin, cloud deployments specialist

    Czech Republic - 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, 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.
