    I am an experienced developer with more than 15 years of active working age. I'm working with C/C++, Perl, Ruby and I'm making cross-platform applications and system tools, text parsers and web applications. I'm also a skilled Asterisk and Freeswitch application developer with an over a 7 years experience. I can solve your issues shortly or I can develop a complex application or I can integrate your business systems with a telephony. Got a problem? I'll fix it! 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 which I have - transparently and on a regular basis. In one word - you can trust me as you trust yourself.  less
