    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.  less
