    Specializing in Server Administration, Configuration, and Deployment

    United States - Last active: 1 day ago - Tests: 5

    I have been in the telecommunications industry for over 13 years and have worked as a consultant to major Fortune 500 companies in the past for both business and technology needs. I have a vast knowledge of anything that relates to the internet, both hardware and software realms and have worked on a variety of projects ranging from the simple to large scale transition ones spanning months at a time. I understand a business' need to get projects done right the first time and have always exceeded my clients goals. If they're not happy, I'm not happy. I have a dual bachelors degree from the University of Colorado at Denver in Business Information Technologies and Business Management. My Masters in Business Administration is in International Business and most IT skills I have picked up on my own or through various courses either online or at the local community college. I look forward to working with you and completing any projects you may have, from the quick fix to an entire server farm rebuild. I am also a word class back end programmer familiar with MySQL, Bash, PHP, Perl, and Python. Please, no front end design work, I don't have an eye for creativity (unless it's something simple of course). I look forward to working with you and any projects you may have for me.

    Web and VoIP(FreeSWITCH, WebRTC) engineer

    Russia - Last active: 4 days ago - Tests: 4 - Portfolio: 2

    I'm a skilled software developer and VoIP engineer with more than 15 years of experience. I'm also a full-stack developer of the convergent systems of voip and web. Playing with Freeswitch, Kazoo, SipXecs, Ruby, Perl, JS(node.js), C/C++ and much, much more - I'm always choosing tools for the task. Probably the most important thing which differs me from others - I'm never working just to gain money. I'm always doing my best to reach your goal the fastest way possible. If you've chosen a non-optimal solution I'll correct it and suggest a more efficient way. I'm never promising something that you're probably expecting to hear instead of the realistic estimate of your project. I'm never lying to my clients and I'm always giving all the information I have - transparently and on a regular basis. In one word - you can trust me as you trust yourself.
