I develop and lead software projects since 2000 year. I spend a lot of time studying new technologies. I myself create new technologies (used by thousands of people now). The purpose of this is to achieve technical and technological efficiency in order to achieve business advantages. I am working on big and complicated projects for businbess. I am interesting in long term collaboration and you will find that I am trusted partner. Our collaboration becomes our common work so I do it like my own work. For communication on this site you can click the button *Here Me* on the page of my profile. This button has a drop-down element *Invitation to the project* if you have already published the project, and then click *Chat* in my bet in the project if I have already made a bid.
