Started as a freelancer programmer, I've quickly grown to highly qualified and valued developer at ELEKS Software where I co-worked with world-famous companies and enterprise products such as SAP, Microsoft Dynamics and other, was a team leader and later a project manager of a growing real-estate management project. I have widely distributed and highly rated professional skills in variety of Informational technologies and other areas. In 2010 I've founded an Internet start-up - a new technology in Internet advertising. Now after my company is growing fine, I'm looking for some interesting work to do to feed my hungry developer's brain. In 2012 I've founded an outsourcing company, Synnergia Solutions, and working now on growing my development resources with highly qualified developers to tightly co-work on lots of interesting projects.
