    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.

    Favio M.

    Full Stack Web Developer

    Mexico - Tests: 12 - Portfolio: 15

    I only work on hourly projects. Thanks! A fast learner and problem solving oriented programmer. I am a Web Developer and loving it! Do contact me to start a discussion about your project and how I can help! Work Policy: * I never bill for learning time. If a feature/project requires me to learn something new, I won't bill you since I'm already adding value via the newly acquired knowledge. * I try to deliver the best quality possible, but this is often a trade-off between time, budget, and the specific project situation. (For example, not all clients would want the time/money investment to create a full unit test suite) * I'll be honest. For example, I like giving suggestions on how to save time/money even if that means less billed hours for me. Frameworks I've used: Zend Framework, CodeIgniter, Drupal, Wordpress, ExpressionEngine, jQuery, YUI, a bit of Symfony, Ruby On Rails, Symfony, Flask. Technologies I've used: SQL, HTML, CSS, Javascript, PHP, Ruby, BASH, mySQL, PostgreSQL, Python.
